Historical Significance
The New Jersey quarter was the third coin released in the 50 State Quarters Program, debuting on May 17, 1999. Its design honors Washington’s historic Delaware crossing during the Revolutionary War, making it one of the strongest history-themed issues in the entire series.
Collectibility
The 1999-S New Jersey silver proof is a strong addition to State Quarter sets, first-year silver proof runs, and Revolutionary War-themed collections. Its 90% silver composition, proof finish, and relatively modest mintage of 804,565 give it stronger collector appeal than the regular clad proof version.
