Clad and silver coins are tough because of all the MD that is so prevalent. And when you throw proofs into the mix, well....

I have gotten many proof sets and haven't seen any MD on them but have noticed that there are some varieties where the doubling looks eerily like MD (to me anyway).

My question is, can MD happen on proof coins as well?

(Or is it not likely to happen because of multiple strikes used for proof coins?)

As always, thanks for any insight. Cliff

MD can happen on proof coins,they use the same type presses.If a die comes loose it does not know if it is making a proof coin or a business strike. Although the press operator is supposed to have a much stricter QC.

Machine Doubling and flat field doubling:















Flat field doubling is when the first strike of the proof coin was over struck with the second strikes Machine Doubling. When the MD happens away from the first strikes devices, then it appears as a normal Machine Doubling issue.

Thanks John1 and Coop.

I assumed it would happen but haven't noticed it till now on a 1961 proof dime that had it on all the obverse devices (not just a few).

And that image of the '63 Lincoln with "Flat Field Doubling" around the 3 is another answer to an unasked question.

Proof coins are supposed to be the the highest level of quality, with zero manufacturing defects.

Error proof coins should be discarded, but as the pictures show, it happens.
Today, U.S. proof coins are struck for collectors in their millions.
Because of the very high level of collector interest in error coins, I guess the Mint has become very tolerant of minor manufacturing defects.

It would be very difficult to find an example of MD on proof coins struck before 1960. Quality control with proof coins was much higher then.

But they don't see it. They don't look as closely as we do. Even the grading companies don't ding a coin because of the Machine Doubling. They just consider it a normal event. It is the collectors who see it.
