I'd say it's not a variety, but rather a die identifier...it looks to me, especially as you can also see the shadow of an 'I', that a coin got stuck in the machine and damaged the die? Or, and I don't know anything about this, do they reuse (grind off [not completely]) the old dies, as they sometimes do with hammered? Thanks for that. Very interesting, and something I'd not considered. I hadn't noticed a shadow 'I' either. Do you mean slightly angled and just to the left of the Tertivs 'I'? if it is it would probably also be in alignment with the wonky lower V'.Reaching for my loupe... Yes, there's also what looks to be a shadow of a letter, maybe V, after the S too?
