1965 Roosevelt Dime--Struck on a Silver Dime Planchet--AU-58 (PCGS).A pleasing example of this elusive error, both sides are lightly toned in wisps of iridescent gold. Lustrous satin surfaces with a bold strike and plenty of satiny luster remaining. This desirable transitional error was struck in the Philadelphia Mint in either 1965 or early 1966, at a time with the facility was producing dimes in both the outgoing 90% silver composition and the incoming copper-nickel clad composition. The former planchets were supposed to be reserved for 1964-dated dies, but a few found their way into presses fitted with 1965-dated dies, as here. A highlight of the wrong planchet errors in the John Whitney Walter Collection, and a find for the specialist.From the John Whitney Walter Collection.
