With Cheapy's statement, it would be about 100 pounds.

You know what that means; time for a Bag of Holding for all dat cash.

Convert it to platinum and it's only 10 pounds. Convert it to precious gemstones and it's the equivalent of pocket change.

Convert it into highly paid mercenaries (5 sp a day) and it's the equivalent of 20,000 lbs of man and steel for 100 days and a 100 men.


I thought it would be much higher. I guess I always saw the gold coins in fantasy as being roughly the size of a silver dollar. Which weighs 1 oz. so I figured it would be more like ~300 lbs.

Liberty's Edge

50 to a pound was about what the old Roman coins weighed. 6-8 grams


I highly doubt that coin minting is standardized is any fantasy setting, so gold coins could range anywhere from the size of a silver dollar (mentioned), to a shirt button. For the sake of ease, it's averaged out.


Just so you have a rules reference:

Thanks!

I just had my PC's just find over 5000 gold, after fighting a minor Jistka clockwork Golem. Next week I'll find out if they are too encumbered and/or have enough bags to carry all that gold 'n treasure. The witch died. bwaaaaaahahaha!

Cut open the witch, and use dried organs as bags?

I used to own some 18th century silver coins that were over 1oz each. I used to break them out whenever people wanted to argue coin weight.


Artanthos:

In general, coins got bigger as time went on. Old coins tend to be smaller than more modern coins. It all depends on the era. 3.X set a value of 50coins to the pound (obviously choosing smaller coins) and PF has stuck with that.

Do keep in mind that "gold piece" in most RPGs, including Pathfinder, is a unit of value, not unit of currency. Since historically precious metal coins derived their value from the value of the metal itself (for most part), debate on the weight of an actual gold coin is moot - Osirian Gold Scarab may be worth 3gp, while Ustalavic Gold Bit may be worth 1/2gp, with former most likely weighing about 6 times more than the latter.

The rule of 50gp/lb is what gives you value of gold - a pound of gold is worth 50gp. That may turn out to be roughly 17 Osirian Scarabs, or 100 Ustalavic Bits, but in the end value originates from the mass of gold, not the imprint or origin of the coin itself. Likewise, in Osirion a merchant may name price for a 30gold dagger as 10 Scarabs, while in Ustalav innkeep will expect one Bit for a 5sp/night room and dinner.

* In real world, various precious metal coins' values were affected by origins as well, mainly due to the fact some states may have been minting less than pure coins; for example Byzantine gold coins, solidi, were valued for being purer in gold than others; in fact, they contributed to the fairly widespread use of term Bezant in medieval Europe for any gold coin, particularly foreign ones. On the other end, german Rheingulden's gold content kept dropping (from original 98% gold to as low as 77%) which no doubt meant that same weight of Rheinguldens was commonly valued lower than Byzantine Solidi.

** Additionally, value of various gold coins was affected by exchange rates - it was common for local merchants and folk in a town or state to accept preferably or exclusively local coinage; a merchant or traveler from afar with foreign currency had to go to a banker to exchange it. At that point, value of his gold became affected by banker's provision rate, as well as relations between the country issuing the coin and locals, etc etc.


Ahhh yes, the fun of Kings debasing their currency. I much prefer a D&Ds non-realistic approach for simplicity. Frankly, I think it can go even farther towards being simple. But that is another discussion.

- Gauss


Also, keep in mind that weights are typically set more for game balance than realism. In another game I play, the standard unit of weight in-game is the AUM (Arbitrary Unit of Mass). It lines up with no existing weight or mass system and isn't necessarily consistent within itself, but it assigns weight of items based on how useful they are rather than how much they would actually encumber you by.


Just a fun fact,

1 cubic foot of gold weighs 1205 U.S. pounds.

So good look stealing that chest full of gold!


We always played 50 coins to a pound.

5,000 coins would be 100 lbs.

Liberty's Edge

It is much simpler to have static weights. There is no Golarion Weights and Measures organization, so would could have regional variances, but that would add a layer of encumbrance tracking burden on the player and the GM. 50 to a pound is fine.


Meh, I usually ignore coin weight. Otherwise people start exchanging their gold into gems all the time, which just adds another layer of confusion.

Sure if they find a chest full of gold that may be different, but talking about their coin purse.


Remember that when converting gp to pp that platinum actually weighs less than gold. By that I mean 5000 gp in platinum weighs even less than one tenth of 5000 gp in gold. You can also have an equal value of silver and it would only weigh 5 not 10 times as much ( because silver is about half the mass of gold per mole). And an equal value in copper coins would only weigh 25 not 100 times as much because copper is about a quarter the mass of gold per mole.

*there is probably not that big of a difference in platinum to gold for most cases. There is only about a one gram difference per mole between the them.

** that one three oz gold coin would weigh approximately 9.5 g which would be about .05 moles of gold.

*** the above assume equal moles of the various metals in each respective coin


Yes, but how many moles of gold are there in a mole of gold?

Since this is the "rules" forum, we'll leave out such issues as chemistry and physics and reference the CRB:

Pathfinder Core Rulebook, page 140 wrote:

That's not the standard gold coin, nor the standard silver. That's the standard, non-"House Rule" coin, regardless of metal.

If your sense of reality requires, you can then assume that, based on differences in density of metals, coins are larger or smaller as necessary to ensure that all coins weigh approximately a third of an ounce.

This is much better than worrying about different size coins (within a metal), densities (between metals), debased currency (except as an intentional plot point), or anything other than 50 coins is a pound. Why? Because that's not the point of the game. Realism is only useful when it doesn't result in people performing calculus to determine encumbrence.

5000gp in platinum weighs 1/10th as much as 5000gp in gold, because platinum is valued at 500gp/lb. Moles don't factor here. You dont exchange 10 moles of gold for 1 mole of platinum.

They should be happy it's not copper!

I can see why that might be a problem. I have trouble getting change for a $20. Imagine trying to get change to pay your bar tab when your gem costs more than the whole bar.

Yall may or may not be interested in this bit of math.

If you make a coin 2mm thick that weighs 1/50 lbs, you'll get the following:
- 1 cp has a diameter of 25.4 mm
- 1 sp has a diameter of 23.5 mm
- 1 gp has a diameter of 17.3 mm
- 1 pp has a diameter of 16.4 mm

For comparison, a US quarter has a thickness of 1.75 mm and a diameter of 24.3 mm. A US dime has a thickness of 1.35 mm and a diameter of 17.9 mm.

I was toying with the idea of making coins in my game perfect cubes or spheres or something so that you needed a wizard or maybe a dwarf to mint coins and not just everyone could do it. But the value is still based on the weight of the metal, so a identify purity cantrip would probably be a better investment long term.


And if those gold coins where pure, the value of those 100lb would be, today, a bit more than 1,800,000$.
There might be some Gygaxium in those coins.


When I do the math and think of the volume gold coins take up it makes me realize that those piles of treasure that even powerful dragons have isn't nearly as impressive as is shown in most artwork. That's even taken into account it being mixed with coins of lesser value and other objects.

Instead of having a large cave with them piled everywhere their stashes likely could only take up the corner of a small room.

What they never tell you is how the dragons like to sculpt mounds out of clay, then press a single layer of coins onto the surface. All the comforts of a gold-lined bed, at one-one-millionth the cost.


Well, Dragons collect precious metals to sink away excess body heat while they rest and for the exfoliating properties so, strictly speaking, they don't need a solid mound; just enough to facilitate the heat exchange.

In the old days of Gygax's AD+D, that'd be 500 lbs.


Yes ... but you could get meeelleeeeooonnnss of gp in a single hoard! *grin*

Then you had to hire carts, porters, drivers and the attendant beasts to haul out all the loot.

Just to deal with the copper and silver.

That was fun way back when! ^_____^

What about a mole of moles


Worth your weight in gold is pretty good these days.

Exiting fantasy for a moment: Which weighs more, a pound of feathers or a pound of gold?

A bit of a trick question really as your unit of measurement is semi ambiguous.

Feathers using imperial weight, are 16 ounces to the pound. Gold measured using troy weights is 12 ounces to the pound.

So depending on the unit of measurement a pound of feathers is in fact heavier than a pound of gold.


5000 gold coins weigh about 45.4 kg (~9 g a coin).

ps: Sry, but at least someone had to promote sensible (i.e. non-imperial) units :P

Verdant Wheel

Here in Brazil we consider each coin to be 10g (the coins are made from different metals, but enogh metal from each so the coins weigh the same). 5000 gp would be 50 Kg.

And if the inventors of that scale had come up with a sensible way of creating it, I would agree.

Official definition of a meter: The meter is defined to be the distance light travels through a vacuum in exactly 1/299792458 seconds.

My stopwatch doesn't react that quick. And that certainly isn't how the original inventors measured it.


Yeah, you should use something sensible like the inch (defined as the length of three barleycorns) or the pound (defined as the weight of 7000 grain seeds from the middle of an ear of barley).


yeah, platinum...

It's super-rare
It's shiny
It's hard to work
It doesn't tarnish or rust
It costs 500gp/lb (That is, if 50 coins in gold is 1 lb, and coins weigh the same, then 50 coins of platinum is 500gp)

contrast mithril

It's super-rare
It's shiny
It works like steel (so, you can presumably cast it, wrought it, forge it, add an edge to it, etc).
It doesn't rust
It's incredibly useful for adventurers, and can be used in jewelry
It costs 500gp/lb for worked items (so, some value to the raw material, plus labor, equals 500 gp/lb)

Why is platinum worth anything at all? It's just obnoxious silver!

(In my game platinum and silver are equal, and it's 10gp = 1mp. Presumably also 6gp = 1ap, but adamantium is hard to work and can possibly rust as well, so no one coins it, except for some weird death cultist dwarves mumble mumble...)

Until the invention of milled and rolled edges the opposite was true, coins got smaller as time went on. Even with milled edges coins sometimes get thinner if they have a significant percentage of gold or silver in the alloy:)

it was 2nd that changed the weight to 50/lb in D&D and AD&D it was 10/lb (and adventurers left a lot of copper and silver coins in the dungeons because it wasn't worth the weight to carry anything less than electrum).

Also note that a chest of gold coins would take up more volume than a solid block of gold, and even more volume if the coins were heaped instead of stacked.

The Exchange

Once D&D got me interested in numismatics, I went to a lot of trouble to learn all sorts of things about coins throughout the millenia. Then, after a few years of devising new coinage systems, shapes, metal types, relative value of mintings, etc., I realized that the only important thing about a coin from the player's perspective is what they can buy with it: 1 gp = 1 gp. This is why players don't usually kick if you switch to a silver standard (giving gold the value of platinum, and kicking platinum back to 1735 where it belongs: let mithral or adamant, fantasy supervaluables, do the job.) As long as chainmail costs 150 wealth units, it doesn't matter to the PCs if those units are called gold, silver, or arsenic.

Why indeed ...


Coin making in a fantasy realm with magical spells and powers would likely be highly uniform and probably include special anti-counterfeiting techniques.

Magic has its uses. And kings hire court wizards for a reason.


There is a 1st level spell for shaping 1 pound of lead into sling bullets.

I'm sure that any wizard worth their salt can twist that spell into:

School transmutation; Level sorcerer/wizard 1
Casting Time 1 round
Components V, S, M (1 pound of soft metal)
Range touch
Target 1 pound of soft metal
Duration instantaneous
Saving Throw none; Spell Resistance no
You convert 1 pound of soft metal into coins or trade bars. When you cast this spell, you decide whether you create normal coins, or bars of various sizes. The spell creates 100 coins, 50 coins , 25 coins , etc.. or trade bars of larger sizes, such as 5, 2, or just a single bar. coins or trade bars need not be in classic shapes, but can be various geometric shapes, from circles to spheres, squares to donuts, triangles to hexagons. The result is unadorned, and must be stamped with whatever kingdoms idenifying mark for their coinage separately.

Abadar, or any deity of civilization, would have a stake in standardizing money transactions. A church can bring a lot of power to bear against a country. Try to go your own way and your money is not accepted elsewhere.

I assume that all money is minted under the watchful eye of Abadar's priests. Market days would be opened by a priest of Abadar blessing the transactions. He would keep a watchful eye on transactions and be available for any disputes.

So, my assumption is that the church of Abadar has come up with a standardization of all legal tender coinage. Must be of X size, weighing Y ounces, with Z% and A% composition. Stamp it how you want as long as it conforms to these standard designations.

Anyway that is how I run it. Gets past that whole nasty exchange rate issue.

wrong: platinum (21450kg/m3) is more dense than gold (19300kg/m3)

silver (10490kg/m3) and copper (8960kg/m3)
