I enjoyed the thread thank you. This coin to me would be a g06. There are about 10 years of early lincolns that required special consideration when grading, the 1922-d being one of them. The easiest of the 4 die variations is this die pair one with the distinctive die cracks. While they are not rare they are not common either. Regardless, the value is unaffected by the variety. (unless you can find a collector that cares, good luck with that). My research has about one in 20 having this error. As minting progressed with die pair one a third die crack is noted at about 9:00. This variety is about one in fifty 1922's. Although not rare if you consider that only about and unconfirmed 800,000 of these pennies left that would mean only 40,000 die pair ones have two cracks and only 16,000 left of the three crack variety. On to die pair four, presumably the last of the die pairs. The reverse is weak and slightly rotated clockwise. The hallmark feature is the coattails effect present due to a worn obverse die. From about 4:00 to 5:00 the coattail is blended in to the edge of the coin looking missing. This coin should be graded by the obverse as the lack of detail on the reverse is due to die condition not wear. Grading is done as a measure of wear. The rear has very little detail and will be unappreciated by many collectors. I find it beautiful as it shows the normal process of an aging die plate. I have not read this but believe two sets of plates where used in four die pairs to make 7 million pennies, fascinating really.
I am working on a book about 1922 cents to be published in 2022. First of all I would like to say that after 15 months of research I would no longer call the ANACS Die Pair #4 variety incredibly rare, as I did above. It is just rare, though tough in nice condition. I have also been able to track it back to an earlier die state before the coat elongates, when it had a different interesting feature that later disappears. There were 20 obverse dies used and 27 reverse dies. I will be adding a few new "Weak D" varieties, and one new "No D" variety. I will also be numbering the die crack varieties, and several other varieties.
Here's my DP1, it's 100% no D regardless of the ANACS designation (they only certify DP2 coins as "no D"):
Wow, Tom, that seems like a *very* specific topic for an entire book. Is there really enough material to warrant a full book? Or is this going to be more like a monograph? This seems like *exactly* the sort of thing that Roger Burdette's attempt at a "Journal of Numismatic Research" would have been good for.
The 1922 gets a little grading slack. On the OP I would go F-12. Now of course another coin that looked like that would be VG-08 but all coins are not graded by the same criteria. My 1922-D does not have a die crack, but it's in decent shape.
