I don't know if Germany is using single-press hubbing, but I agree in principle that we need a separate designation for the die doubling that can occur with single press. As you point out, it's basically the same as MD on a coin except that it occurs to the die. It's a "machine doubled die" obverse or reverse - an MDDO or MDDR, and not a DDO or DDR. I think it would be good to distinguish them. Fat chance that anyone will start doing that though.
Not yet. They’re at ICG and I’ll update here and my post about this submission when I get results. Frankly, I find the whole effort to designate doubling on a hub or die as anything other than a doubled die to be silly. Strike/machine doubling is reserved for the time in which the die strikes the planchet. If someone wants to clarify that it’s a doubled die from a single press hubbing, go for it. But the die is still doubled, and the doubled die struck the doubled image onto the coins. It feels like we are making arguments for no reason and I’m not seeing the added value in this discussion. The die is doubled. This year and mint is the only one I’ve found that has this doubling, and I’ve been watching Germany’s 2€ coins for a while. Not saying it’s the only one, but it’s the only one I’ve ever seen.
It's not that important but I don't agree that it's silly. It would impart knowledge and I'm a big fan of being specific.
I should have clarified that what I perceive as someone’s effort to treat the coin as not being a doubled die is silly. I’m all for specificity, but this coin is not machine/strike doubled. It was struck on a doubled die. How that die got doubled is certainly up for discussion, but @eddiespin came off as a condescending “that’s not even a doubled die” and I don’t see the value/merit in this argument/approach. It’s very possible I misunderstood his intent, but it seemed unnecessarily caustic.
Here are some photos of the coins I submitted to ICG. @paddyman98 hopefully these are more clear. These look to me like the middle/second “stage” I shared. I have a few of the very strong doubling, but none that are submission worthy yet (most are pretty circulated). All photos are the same coin, just changing lighting, angle, etc.
