Columbia Mint was a precious metals investment company in existence from 1974 to 1983. The company was based in Delaware and was one of several corporations that were owned and operated David and Francis Margulies. In the mid 1970's they produced quite a few silver art bars. In the early 1980's they began to branch out into reproducing miniature gold coins such as the 1908 St. Gaudens.
