Coins of Cthulhu
Here's something to make a sailor tremble:
Innsmouth Gold coins have washed ashore, and are now available for order.
Originally created for Chaosium for the Call of Cthulhu RPG, these ancient and terrible coins feature eldritch symbols and strange octopoid figures. The coins are designed to look worn and old. The designs are by Mark Helwig, and there are three different coins in the set.
If you have high sanity, these coins are available in 10-packs and collector packs.
