Inspired by other coin sorting designs seen here, I wanted to make a U.S. coin sorter for my oldest daughter. We needed space for lots of pennies as well as a spot for gold dollar coins (what kid doesn't love a magical gold coin). After three iterations, this was the final design I settled on. Includes two penny columns, nickel column, dime column, quarter column, and Sacagawea gold dollar coin column. Currently testing a revolving peg for the center, so once that's ironed out, I'll upload it.
