This was issued as part of one of the most popular series of coins in the world, the United States Quarter set. Fifty quarters over 10 years, representing five States that joined the Union. The coins are in Proof condition in a double-sided display case, they are rather beautiful and interesting. Illinois with Lincoln, Alabama with Helen Keller, Maine with a lighthouse, Missouri with the arch and Arkansas wheat and a diamond. Washington is on the front of each coin with ‘In God We Trust’. This set is most interesting as most people don’t know a lot about the States represented.
