1982 Lg. Zinc LMC DDO?

1982 is a tough year when it comes to DDO's. The large date really seems to mess with my perception.

With that said, yours does seem to have some thickness on LIBERTY and IGWT. It's hard to tell because I can't see many markers but you might have WDDO-004. Here's the link.

I think I see a matching die scratch going NE from the top of the B (LIBERTY) and the right arm of the Y looks thicker as well.

Nice images by the way and congratulations if you are able to confirm the variety.

It looks like both dies have been heavily polished. I took some close ups where they polished. Chin and neck completely filled in. Die markers for WDDR-004 are vertical lines on obverse and reverse. They missed some of vertical lines. They did a better job behind the back but few left below LIBERTY. On reverse arrows point to some are barely left. There's more but I can't get them to focus. The third picture is behind back. Lol we'll see what others have to say.

I'll check tomorrow on obverse. Here's overlay I did for reverse. First picture 004. Second is where I'm able to see them on my coin where the arrows lined up. Looks pretty close. Thank you for your obverse shot.
