1964 vs. 1965 Quarter: Silver Content, Value, and How to Tell the Difference
A standard 1964 Washington quarter is 90% silver and contains about 0.18084 troy ounce of silver. A standard 1965 quarter is copper-nickel clad and contains no silver. The fastest checks are the date, edge and weight: about 6.25 grams for 1964 versus 5.67 grams for 1965.
- 1964 quarter: 90% silver, 10% copper.
- 1965 quarter: copper core with copper-nickel outer layers.
- Both are 24.3 mm across, so diameter alone does not separate them.
- A 1964 quarter has a silver-colored edge; a normal 1965 quarter usually shows a copper band.
- Condition, mintmark, errors and varieties can create collector value above metal value.

The change was not a subtle adjustment. The Coinage Act of 1965 moved circulating dimes and quarters away from silver as the United States responded to a coin shortage and rising demand for silver. The Mint continued striking coins dated 1964 after the calendar year ended, while 1965-dated clad quarters were produced later. That is why the date identifies the standard composition more reliably than guessing when the coin physically came off the press.
How much silver is in a 1964 quarter?
A new 1964 Washington quarter weighs 6.25 grams and is 90% silver. Multiplying the gross weight by .900 gives 5.625 grams of fine silver. Dividing by 31.1034768 grams per troy ounce gives approximately 0.18084 troy ounce. For circulated 90% silver sold by face value, dealers commonly use approximately 0.715 troy ounce per $1 face value to allow for ordinary wear.
Common circulated-trade convention: approximately 0.715 troy ounce per $1 face value
Do not confuse face value, melt value and collector value. The coin says twenty-five cents, but its silver content creates a metal-value floor. A high-grade coin, attractive original example, recognized variety or mint error may be worth more. A damaged or heavily worn coin may trade mainly with ordinary 90% silver.
For a current calculation, use Agate’s silver coin melt-value guide. Record the spot source and time because silver prices move and a dealer bid is not the same as theoretical melt value.
How to tell whether the quarter is silver
Use the checks together. Edge color alone can be obscured by dirt, plating or damage. A kitchen scale may not be precise enough. A counterfeit or altered coin can also imitate one feature while failing another. Agate’s broader guide on how to identify silver coins explains why date, edge, weight and product-specific references should be combined.
What about a 1965 quarter with a silver-looking edge?
Do not assume it is a valuable transitional error. First rule out plating, environmental discoloration, a filed edge, an inaccurate scale or an altered date. Genuine wrong-planchet and off-metal errors require specialist authentication because the value claim depends on what the coin actually is, not what one photograph appears to show.
Preserve an unusual coin exactly as found. Do not clean, scratch, file, drill or acid-test it. Photograph both sides and the full edge, record its weight with a calibrated scale and submit it to a qualified dealer or recognized grading service when the evidence justifies the cost.
How much is a 1964 or 1965 quarter worth?
For an ordinary circulated 1964 quarter, start with silver content. The theoretical metal baseline is:
A dealer’s offer may be below, at or above that calculation depending on quantity, local demand, verification, condition and the dealer’s spread. Retail replacement cost will normally be higher than a buyback bid.
A common circulated 1965 quarter generally remains a twenty-five-cent coin unless condition, a documented variety or a genuine mint error creates collector demand. Do not use a rare auction result to value an ordinary pocket coin. Compare the exact date, mint, variety, grade and certification status.

Is every 1964 quarter made of silver?
Standard U.S. 1964 Washington quarters are 90% silver. Counterfeits, altered coins and unusual mint errors require separate evaluation.
Does a 1965 quarter contain any silver?
A normal 1965 circulation quarter contains no silver. It has copper-nickel outer layers bonded to a copper core.
Why is a 1964 quarter heavier?
The silver-alloy standard weighs about 6.25 grams, while the clad standard weighs about 5.67 grams. The coins have approximately the same diameter.
Can I use the ring test?
Sound can be a screening clue, but it is subjective and can damage a coin if done carelessly. Date, edge, precise weight and professional testing are safer evidence.
Should I clean a silver quarter before selling it?
No. Cleaning can damage the surface and reduce collector appeal. Leave the coin as found and let the buyer evaluate it.
