The 1999 State and Territorial Quarters are part of the 50 State Quarters Program initiated by the United States Mint, designed to honor each of the 50 states with a unique reverse design. The quarters from 1999 feature designs representing Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut. Coins minted in Denver during this year can be identified by the "D" mint mark, found on the reverse side. These quarters are popular among collectors due to their historical significance and the novelty of the state-themed designs.
