2022 P Quarter: Doubled Strike Doubling?

So now I think I may understand your idea of whether or not there is a master hub still and not just a master die. If when the master die was being created from the master hub and this doubling occurred, then that could explain the extreme numbers of this anomaly. Why could this not occur in this way as Machine Doubling, from the master hub to the master die? I know it should not, should have been caught but still possible, I suppose. Am I on the right track in your thinking, Pete or have I just muddled the waters a bit more?

If this a possibility, then would this be call "master Machine Doubling" instead?

It favors Machine Doubling but some known examples of doubled dies favor it too, at least to me, especially in clad coins. If many of the quarter and dime examples were not cataloged as doubled dies, I would write them off as Machine Doubling. Here is an example of a proof dime I found in a large batch I bought a few years ago that is a DDO / DDR example and would have thought it to be Machine Doubling if not for the listing.

very interesting Jon.

So did you read everything, Chase? The pic is from a listed doubled master.

I agree with Chase and this would mean it is mis attributed. It is a doubled working hub (at best).

All good, Pete. I usually backcheck things and did not this time, just assumed this was from a listing. You know what they say about assuming. And here I am.
