Having 12 coins together provided a rare opportunity to perform a die study

I recently had the opportunity to examine a dozen examples of the 1964-D Washington, Reverse of 1965 quarter dollars.

Also called Type C Reverse quarter dollars, these 90 percent silver coins display crisp feather detail on the eagle, a design change initiated to accommodate striking the Washington quarter dollar on a copper-nickel clad planchet. It is a popular variety, worth about $225 in Mint State 65 compared to less than $20 for standard reverse 1964-D quarter dollars.

No one knows precisely how many 1964-D Washington, Reverse of 1965 quarter dollars were struck. Having 12 coins together provided a rare opportunity to perform a die study. My colleagues and I were able to attribute the coins to two different reverse dies. This means that dies intended to strike copper-nickel clad coins were instead impressed with a D Mint mark and used to strike silver counterparts – and it happened more than once. It’s exciting to think this mishap occurred multiple times, providing some insight into the transition from silver to clad coinage.

In 1965 when phasing out silver coinage, the Treasury wanted to remove any possible impediment to the introduction of copper-nickel. One concern was that silver quarter dollars would be hoarded, so they produced an enormous number of them.

The 1964-D quarter dollar has the highest mintage of any silver Washington quarter dollar – 704,135,528 pieces. But these coins were not all struck in 1964.

Coinage of silver quarter dollars was continued alongside production of copper-nickel clad quarter dollars until 1967 to meet demand.

An enormous amount of clad quarter dollars were also produced in 1965, more than 1.8 billion of them.

All U.S. coins dated 1965 through 1967 were struck without Mint marks although they were produced at all Mints. The use of Mint marks was temporarily suspended primarily to discourage collectors and speculators from hoarding new issues.

With such an extraordinary number of coins being produced during this period, it is hardly surprising that occasional mishaps like the 1964-D Washington, Reverse of 1965 quarter dollar occurred. Wrong planchet errors from this period also exist and are highly coveted.
