Strange coins

About the coins:
Whilst magic in no way these coins are none the less and insteresting find.

Well concealed in a sack behind a rock in a random cave section of the ruins that Maenae sent the party to to slay an ancient minor evil the party found 15,697 strange ancient triangular silver coins. The sack the contained them was a Bag of Holding.

When they returned to the oracle the showed the coins to an artifacier/art dealer that was visiting Maenae at the oracle, all he could tell them was that they were coins of varying ages, but all old from a place called Vermil.

Nothing new has been discovered of these coins since, all that anyone is able to find out is there place of origin, however becasue they are unusual looking coins merchants reaction when offered the coins are somewhat varied, they may refuse to acccept them as legal tender, only accept them as half silvers, treat them as regular silver, or possibly even be a collector of strange coins and treat them as electrum pieces, offering to buy additional coins if the purchase made was a small one.

Origin of the Item:
This item was from Shrine of the Oracle all that was mentioned was that they were ancient coins triangular in shape, that there were 15.697 of them in the hidden bag of holding and that they were from the forgotten Kingdom of Vermil.

To me this says they should be considered as an unusual coin should someone start trying to spend them in exchange for goods or services and I made a small merchant reaction table, where a d6 roll determines how the merchant will react to the coins, making it effectively a random value currency that the players are carrying around with them.

Here is the reaction table:

Later Developments:
It later turned out that a secret order of immortal warriors known as the sleepless were using the appearance of these coins to track their sworn enemies accross the world, by spending them in various towns accross the kingdom the Party attracted the attention of these godlike golden warriors
