The Mazes Darkness and Treasure coins were made for our friends at 9th Level Games for their Mazes RPG Kickstarter. The design by Chris O'Neill has a crowned skull on one side, and the 9th Level magic circle on the other.
The coins are 25mm diameter (like a US quarter), finished in Antique Copper, and come as a set of 9 coins.
Mazes is a thoroughly modern take on the original RPG of dragons, dice, and dungeons. The first TTRPG to use the polymorph system, Mazes is easy to learn and teach, and ready to play without a lot of prep. For more about Mazes, visit 9th Level Games.
