Few American rarities have been so carefully documented and studied for provenance as the 1823/2 Capped Bust quarters. In fact, it is posited that the four rarest U.S. silver coins are the 1802 half dime, the quarters of 1823 (all of which are 1823/2) and 1827, and the 1804 dollar, helping to contextualize the truly elusive nature of this issue.
The reason for the 1823/2 date is because the mint used an 1822 die and simply superimposed a 3 over the 2 in the fourth position. If you look closely, you can still see the 2 beneath the 3.
