Mule Coin that's a Penny on one side and a Dime on the other. I got it from SOUTH COUNTY COIN store in St. Louis, Missouri it was in a penny roll from USA Bank in South Saint Louis County, Missouri. Shipped with USPS First Class. Mule coins were deliberately produced by US Mint employees for sale to coin collectors in the mid-1800s. However, no authentic (accidental) mules of United States currency were known to exist. This changed in the 1990s, when a Lincoln cent (dated 1993-D) with the reverse of a Roosevelt dime were discovered.
This unique mule die clash discovery coin shows the mule clash on the reverse side. There is an arc of incuse letters. Upon careful examination, there are two sets of letters, meaning that the two dies clashed two separate times, at a slight rotation.
It is interesting to note that after almost 20 years, no other examples of this mule die clash reverse are known or have been authenticated and certified by PCGS, NGC or ANACS.
