These are very valuable silver American quarters and not a lot of people know it. Keep scrolling to learn about the 1964 quarter value, variety types, and which one is the rarest.
Rare Silver Quarter Varieties
Called the Type C Reverse, or (RDV-003,) these 90 percent silver coins display crisp feather detail on the eagle. They also show close spacing between the E and the S of States, and a serif on the top-right of the N in UNUM. You’ll need a loupe to see the difference. I used a Carson zOrb coin microscope to capture these images.
The design change was initiated to accommodate striking 1965 Washington quarter dollars on a copper-nickel clad planchet. A 1964 silver quarter weighs 6.25 grams, and a 1965 clad quarter weighs 5.67 grams. Look at the rim and weigh your 1965 quarters with a coin scale.
Some 1965 silver quarters are extremely valuable for this mix up also. For instance, coin dies intended to strike copper-nickel clad coins were instead impressed with a D Mint mark and used to strike silver counterparts.– coinworld.com.Â
Rare Transitional Quarter Errors
Three transitional reverse styles exist among 1964 silver quarters. They are the Type A (normal), Type B (meant for proof dies), and Type C (meant for use in 1965). – error-ref.com. Â
Look for Transitional 1965 Quarter Errors
Type C is the only transitional reverse error. Use a Digital Pocket Scale (0.01g) to verify the standard weight of 5.67g (clad) vs. the rare 6.25 grams. Remember to check any 1965 quarters if you suspect it might be silver. The edge test is helpful, (no copper showing,) but the coin scale verifies.

1964-D RPM D/D RPM Quarter
A repunched mint mark occurs when the letter punch used to punch the mint mark into the die leaves two or more offset impressions, causing an overlap. However, RPM quarters with a completely separate secondary mint mark is a rarity. – ERROR-REF
Compare to multiple images of a 1964-D Washington quarter RPM D/D Mint mark variety. There are many and you’ll need a coin loupe to see this error. Such errors and varieties increase the value of 1964 quarters.
Silver Coin Errors and Varieties
Die cracks and chips are common on coins, and those markings are how varieties get their name. For instance, the bird with the twig quarter is formed by a die gouge.Â
Silver coins are no exception. Bookmark this silver coin error list for future reference. Die markings are useful for determining the age or stage of a die. Die cracks and breaks that earn nicknames become highly sought afterwards.  This makes the 1964 us quarter worth money.
