From the preview:
Over the last year and a half, we've been creating 15 new coin sets for use in board games, RPG's, LARP and as costume props. Each set has 3 different designs based on the fantasy currency system of copper, silver, and gold. Every coin we make takes about a month of research and development; we set our standards high and only the very best coins make it to production.
We're listing our project here to gather pre-launch feedback, enable a better count, help us fine tune reward levels, and to give all our backers the best possible price.
