Did I get the terminology & identifying correct? Part of the bow tie is missing on obverse (grease filled Die I imagine) but I also see a clash mark under it (both indicated by arrows). The reverse gets crazy.. deep abrading going every direction throughout.. clash marks in bays 3,5,6,7,8,9. Columns 3,4,7,8,9 are deformed at the top. On maddieclashes.com TDC-1c-1983-04 looks like this coin but mine doesn't have the Y in bay 2, only scratches.
Although you've got the coin figured out appropriately, some of what you're seeing is the result of polishing as well, likely as a result of the clash. That was the cause of most of the loss of detail. However it got there, though, this die was on its' last legs.
Shouldn't a die-clash result in an incuse, mirror image of Abe Lincoln to appear on the reverse? Here's an example from my collection of a die clash that demonstrates this well: You can see an incuse, mirror image of the outline of Julia Maesa's portrait underneath the figure of Juno on the reverse.
Not always! That's the thing about clashes. You never know where they are going to "strike". If you want to see clashes that show up all over the place, the series of Morgan dollars is the best place to find them. Chris
If the reverse die is softer than the obv die , yes. But in this case a mint worker has used an emory stick to grind off the traces of the clash. (And in their place left heavy die scratches. The Mint calls this "stoning" the dies. It's not the same thing as when they polish them on a rotating lap. But collectors tend to call either one "polishing".)
Well going by the photos on Maddieclashes.com, my coin exhibits clashing in the same areas. Here's my coin, And here's the one from Maddieclashes.com I think my coin is from one of these two events but someone came along & sanded the reverse a bit more & changed out the obverse. Lol
