Advice on "Learning" a new Divine spell

[BlarkNipnar]

So in my campaign I treat currency as actually magical -> distilled magic in coin form. What this does is provide an explanation as to why a guy has to put money "into" a piece of paper to create a scroll, to put money into crafting even when doing it themselves, etc; and why these things have value.

Regardless of what you think of that, I was thinking a new Cantrip for my party (who is in a town with no one to sell to) that "turns an item into gold" essentially, for the sake of getting the "currency" or "magic" out of it.

This cantrip is going to be discovered along part of the adventure and granted to the casters. That said, while Wizards and things can learn spells, divine casters just kinda.. have them if I understand right.

Given that, how do I "give" new (completely non-existent) spells to Divines? Is there a better way to do this?

Maybe I have to give them a "Midas Hammer" instead of a spell?

____
Note: The nice thing about a Cantrip that allows you to do this, requiring concentration, etc, is that you can't then go Midas Hammer someone else's weapon and you know it won't work on Creatures and stuff; meaning the players will instantly understand its use, rather than a Midas Hammer offering solutions to encounters that is potentially overly easy.

Thanks!

Maybe their God shows it to them in a dream, and then they have full access.

There are several options I can see.

1) It was always there but your PCs have never used it. Simply ask them to suspend disbelief.

2) It was always there, but your PCs didn't know about it. Without knowing it existed, they couldn't ask for it from their diety

3) It wasn't available until someone understood the principles of magic well enough to put it together (and related to 2, ask in the right way) now that someone has researched it, those who know are able to ask a deity for it.

Have the PC invent it themselves, it'll be more fun.

Independent Research: A divine spellcaster can also research a spell independently, much as an arcane spellcaster can. Only the creator of such a spell can prepare and cast it, unless she decides to share it with others.

Independent Research: A wizard can also research a spell independently, duplicating an existing spell or creating an entirely new one. The cost to research a new spell, and the time required, are left up to GM discretion, but it should probably take at least 1 week and cost at least 1,000 gp per level of the spell to be researched. This should also require a number of Spellcraft and Knowledge (arcana) checks.

Presumably the divine spellcaster makes Spellcraft & Knowledge(religion) checks instead. Congratulations, you invented a new prayer!

Well, the way Divine preparation works in Pathfinder is at a certain pre-determined portion of the day you get flooded with Divine Power and you channel that power into your spell preparation. Technically your divine bond to a greater being only provides raw power. It is up to the caster to shape that power into spells.

So its possible for one caster to know spells that other casters don't know. You have to be aware of a spell to be able to cast it. This not only explains the difference between 2 different clerics of Desna not being able to cast all the same spells, but even one of them knowing metamagic feats that the other doesn't have access to. It is because the final form of the divine power bestowed upon them is shaped by the caster, not the divine agent providing the raw power.
