In 1997, President Bill Clinton signed the 50 State Commemorative Coin Program Act. This act aimed to reinvigorate the hobby of numismatics by commemorating each and every state with its own unique quarter design. The obverse of each of these 50 quarters showcases a specifically tailored design that is emblematic of a state`s unique history, traditions, and symbols. The 50 quarters in this set are all struck from 90% silver and graded Proof 69 with DCAM designations by PCGS. Compared to their clad counterparts, these Silver State Quarters have a much lower mintage, which makes them significantly rarer to come across.
