Silver Content

Because the 1964 quarter is silver, many collectors and sellers reference the current silver melt value to determine a base price before factoring in condition and collector demand.
What Impacts Value Most
- Condition / Grade: The most important pricing factor
- Mint Mark / Strike Type: Proof and high-grade Mint State coins carry premiums
- Eye Appeal: Luster, strike quality, and surface preservation matter
- Originality: Coins that have not been cleaned typically sell for more
