1964 Quarter Value: Silver Melt and Collectibility
A 1964 quarter has two separate value questions: the silver estimate and any collector premium. Identify the date and mint mark before putting a coin into a mixed silver lot. The silver calculation does not establish authenticity, condition or a sale price.

Price may be out of date. The saved quote is older than 36 hours or flagged stale. Check the source before relying on a metal estimate.
Melt value is an estimate of the silver content only, at the dated spot price shown. It is not an offer to buy or sell, and not investment advice. Dealer offers are often below melt, and collectible coins can be worth more.
Silver content and the formula
Nominal total weight: 6.25 g. Composition: 90% silver. Silver content: 5.625 g, approximately 0.18085 troy ounces per coin.
Standard weight and fineness set by the Coinage Act of 1873, sections 13 and 15 (linked below). Ounce values are rounded for display; calculations use silver grams divided by 31.1034768.
Melt value (USD) = (5.625 g ÷ 31.1034768 g/ozt) × silver spot (USD/ozt).
Source: Coinage Act of 1873, sections 13 and 15, 17 Stat. 426-427. Nominal original weights are used; wear and loss of metal can lower actual silver content. A troy ounce is different from the ordinary household ounce.
What can make one worth more?
The large manufacturing totals show why the date alone does not establish rarity. A proof finish, unusual strike or exceptional preservation needs inspection; this page does not assign a grade or a premium.
Date, mint mark and condition
The Mint report counts pieces bearing 1964 across production through April 1966; calendar-year production is a different measure.
Keep the date, mint and any suspected variety together in your notes. A mint mark identifies a production location; it is not a grade. Preserve the surfaces rather than cleaning a coin to make it look brighter. If an unusual coin warrants professional assessment, have it graded by PCGS or NGC; neither service sponsors this guide.
Suspected errors need authentication
Doubled-looking letters, a weak design or unusual color can have more than one explanation. This guide does not identify an error variety from a description or assign a premium. A damaged or altered coin is not automatically a mint error. Obtain an independent assessment before attaching a variety name or collectible value.
Mint-report production records
These are the manufacturing counts and categories stated in the linked Mint publications, not a survival census or a grade-price table. They can include proofs, assay pieces and production outside the year on the coin. They should not be substituted silently for circulation-strike catalog mintages.
