These two quarters are suffering from Die Deterioration Doubling.

To CCF! To me, they don't get any respect because they're super common to find. I find them all the time CRH (Coin Roll Hunting). Also, they are often on ebay and other websites being mislabeled as a Doubled Die when they're not.

Great examples of DDD can be found on many early 1980s nickels, an era when the mint worked those dies to death.

Mike, with that wide Machine Doubling on Lincoln's profile, why isn't there also much on IGWT?

Wow, that 1991 cent is amazing.. Is that a variety or a unique error?

Why are grains of sand not as valuable as gold? They are common.

IN GOD WE TRUST is not affected on this 1991 cent because its relief is lower. The die bounced up after impact, shifted to the left, and landed on the design with a bit of a secondary bounce. The die didn't sink into the design deeply enough to affect the motto.

CoinHI, this is clearly not a die variety because the abnormality is related to the strike, not the die. There are other examples of Machine Doubling that approach or match this level of severity. So it's not unique by any means, although examples this extreme are quite rare. The year 1991 produced some outstanding examples of double-sided Machine Doubling, of which this is one. I didn't bother showing the doubling on the reverse face.

In case anybody's curious, my take on when the minting process ends is when a coin leaves the striking chamber for the last time. Any mishap that occurs within the striking chamber, or that affects the protruding portion of an off-center or expanded coin while the rest of the coin remains inside the striking chamber, is a mint error. The defect must be one that could not occur outside the coining press. Of course, the end of the minting process occurs later for small dollar coins with edge lettering. The lettering is applied well after the dollar has left the press. The advantage of my definition is that it incorporates such eye-catching phenomena as ejection impact doubling.

What Mr.Diamond said makes perfect sense. Here is a 1983 P, first quad MD I have ever heard of or have ever seen.

That's an impressive number of shelves. I don't recall seeing a number greater than that on domestic coins.

Mr. Diamond, when I first saw this under magnification I thought I found a new DDR! It's in a 2x2 and is really quite impressive to see in hand.

@MikeDiamond I like your cutoff point of the striking process ending when the coin leaves the striking chamber for the final time. Makes far more sense and captures errors like double denomination, die caps, and double strikes.
