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 Quarters

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 coin microscope to see the difference.  I used a Carson zOrb 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.

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.

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.

Type C is the Rarest 1964 Quarter

The 1964-D Type C die variety is scarce, therefore even the lowest grades have higher premiums, but all 1964 quarters, regardless of grade, are worth more than face value due to their silver metal content.  

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.

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 a die gouge. 

Silver coins are no exception.  Die markings are useful for determining the age or stage of a die.  Die cracks and breaks that earn nicknames become highly sought afterwards.
