What This Coin Looks Like (Obverse, Reverse, Mint Mark Location, Special Features, etc.): One major variety is the 1880/79 O Morgan Silver Dollar with an 80/79 overdate from the New Orleans Mint. This coin features an 1880 date struck over the previous year of 1879 date - which resulted in an 80 over 79 date. This variety is fairly easy to identify because the underlying "7" is clearly visible within the top part of the "8". A small piece of the underlying "9" is also seen inside the "0" at the upper-right side. The difference between the 1880 O normal date vs 1880/79 (80 over 79) Morgan dollar varieties is depicted below in the example comparison image:
