Fantasy RPG Coins

Pay your RPG players in physical gold and silver pieces instead of just pencil marks on character sheets! These coins are broadly inspired by the coinage in the _Dungeons & Dragons_ world of the Forgotten Realms, but designed for 3D printing, with one flat side and easily printable details on the other side. Any standard desktop printer should be able to print these no problem, with no supports. This thing includes copper, silver, gold, and platinum pieces, along with small gold bars and platinum bars that can be worth 100x or 1,000x an equivalent coin.
