In a previous topic listed below, a couple of members and I were wondering if the majority of 1982 Zinc Large Dates have the same doubling from a working hub. Opinions are definitely welcome, and pictures of 1982 zinc large dates are also in need. Hopefully, we can discern the cause of the doubling!

Now that I think about it, doubled working hub may not be the right classification. Doubled Master Die? Because of how common the extra thickness is, there'd have to be numerous working hubs with the doubling.

My opinion on the current 1982 DDO Listings:
1982 Cu DDO-001/WDDO-002 (FS-101) is clearly a doubled die
1982 Zn DDO-002 is stronger than the Doubled Master Die, is a doubled die
1982 Cu DDO-003 is stronger than the Doubled Master Die, is a doubled die
1982 Cu WDDO-001 is Doubled Master Die
1982 Zn WDDO-003 is just die abrasion doubling, but that's been talked about before and off topic
1982 Cu WDDO-004 is Doubled Master Die
1982 Cu WDDO-005 is clearly a doubled die
1982 Zn WDDO-006 is Doubled Master Die
1982-D Zn DDO-001/WDDO-003 is a doubled die (doubled ear and hair) with the Doubled Master Die (LIBERTY and IGWT)
1982-D Zn WDDO-001/1DO-001 (SMALL DATE) Minor, but still a DDO
1982-D Zn WDDO-002/1DO-002 is stronger than the doubled master die, is a doubled die

The master hub was showing a lot of wear, thus the need for a new small date to replace the aging master hub.

Very interesting thread. I have been wondering as well too, since I see plenty of them with the same doubling.

At the risk of being off-topic, die abrasion doubling (WDDO-003) really just means Die Deterioration Doubling, yes? I think Tanner's probably exactly right about these, not that I'm some sort of pro, but all those opinions make sense from what I see.

Die abrasion doubling does appear like Die Deterioration, but has a different cause. Die abrasion is caused by the removing of die clash marks.

From Wexler:


Quote:
The technique for removing these die clash marks is to rub the surface of the die with an abrasive. If the die is abraded too vigorously in the area of the incuse design elements, the abrasive will eat into the surface of the die in those areas very much like the erosion that takes place in normal Die Deterioration. Again, these depressed areas from the abrasion process will appear as raised areas on the struck coins resulting in "doubling" of the affected letters or other design elements.

Ah, I got you. I had looked at Mike D's entry instead, and he says no such thing if I'm following him correctly. http://www.error-ref.com/abrasion-doubling/

Definitely getting off topic now. But to be honest I have not seen Mike Diamond's article about it, I guess there's differing opinions. Regardless of the cause, it's not a doubled die.

Sorry, didn't think it was veering that far off, but to bring it back to "the topic", what more is needed to make a determination here? I get the impression it's pretty much a foregone conclusion at this point.
