1964 D Quarter Transitional Error?

So, we know that some 90% silver quarters dated 1964 were actually minted in 1965 with the wrong reverse die. I am assuming that this was because the mint had many 90% silver planchets left over and obviously couldn't use them for anything else. Was this true of dimes and halves as well? Were there 90% silver dimes and halves dated 1964 that were actually minted in early 1965? Does anyone know? And were there die differences, too?

How about a clearer image of the reverse .
That will make everything easier .

 

This had nothing to do with the left over planchets. It was all due to the change from silver to clad. The public began to hoard the silver. In order to make the public believe that everything would be fine they minted dimes and quarters (not sure of the halfs) and supplemented them in with the change for a couple of years.

 

Due to the coin shortage the 1964 date was frozen in 1964, the coinage act of 1965 which approved the use of the clad composition was not signed into law until July 23, 1965 so all during the first half of 1965 the coins produced were dated 1964.

Another provision in the act of 1965 was that silver coins produced after the passing of the act would continue to be dated 1964 and silver coin production would continue alongside the clad production until sufficient clad coinage had been produced to sustain commerce. The first 1965 dated coins came along in the third quarter of 1965 (Quarters began in August 1965, dimes and half dollars started in December. Cents and five cents probably started immediately as the 1964 date freeze no longer applied to them.) and the silver coin production lasted into 1966 with the last 1964 quarters being made in January 1966, the last dimes in February, and the last 90% silver halves in April.

AS far as I know there are no reverse die differences between the 1964 and 1965 dimes and halves.
