How much would a basilisk egg go for?

[CoI]

PC's raided a nest recently and took all the eggs. Before it comes up I'd like to have a GP value on it for them. I've looked and can't find anything similar anywhere. And no, they aren't hatching and raising them. ...they're doing that with the mythic ones they found :/

Not sure if it's helpful at all, but the closest I oculd find is griffon eggs being listed as costing 3500gp, though they are cr4 while basilisks are cr5.
It might be a bit hard to find someone who would be willing to buy the eggs of such a dangerous creature though.

[Elder Basilisk]

Basilisk eggs are pretty close to the definition of an item with a very limited market.

Griffin eggs are much closer to a widely marketable commodity. They're expensive, griffins are difficult to train when you hatch them and expensive to feed when you've trained them but they make an impressive mount with useful abilities that most mounted warriors would be able to take advantage of.

Basilisks, on the other hand, are not really useful as mounts and are far more dangerous to their handlers (unless perhaps you are selling them to grimlocks). If you want a basilisk, it is probably because you want to guard a vault somewhere--and you hardly ever need to access the vault. Or maybe because you like making statues out of people. Now, if you do want something to fill that purpose, basilisks are very good at it, but most people--even most people with money--don't need something to fill those purposes. Consequently, the challenge of selling a basilisk egg is going to be finding someone who wants it. If you do find someone who wants it, you can probably name your own price so anywhere between 3500gp and 10,000gp is probably fine.

But finding someone who wants it should be a challenge. Consider the contrast. If you were giving them away, most wealthy warriors would probably be interested in the griffin eggs. That's why they're expensive: because lots of people want them and they're hard to get. On the other hand, even if you were giving them away, most people would not want the basilisk eggs.

And do try to find a buyer quickly. If the eggs begin to hatch while still in your possession, that could be extremely bad news for you and everybody nearby.

Which also brings to mind city laws. Considering the hazard they pose, I do not know many cities that would not consider basilisk eggs a dangerous good. Mere possession of it might get you exiled or even executed.

Is the gold really worth it? It may be better to destroy the eggs.

Two other possibilities for markets are a wizard/ alchemist guild/ college or thingy buying them for research or as rare components for whatever.
