Hi, I am looking for flat field doubling quarters for the period from 1950 till 1974 inclusive.

Any photos will be well appreciate or willing to sell.

Thanks, Silvio

PS: The deffinition for Flat field doubling


Quote:
This coin exhibits dual images as a result of having its machine doubled image flattened by the second strike of a proof coin. This is a very common phenomenon on proof coins from 1950-1974.

This could be find more in Cents and Nickels after 1974 and not for Proof coins, but also for business strike.
