There's got to be a chance, I suppose? There would be space for the stop to be entirely hidden under that i, and there could've been more than one die re-used this way. However, I wouldn't buy it as one, though, as I'd definitely want a 'peeping stop' die-variety to substantiate the claim. There must be endless varieties out there, which are now impossible to 100% confirm, it's only in cases such as your suggested part showing stop, that you can name it. Unless other die features clearly link it to a li obverse.... Without a long-winded post, I think you know where I'm coming from. Basically, without other die identifiers, I don't see how he, or anyone else, could ever call it ii/i He can call it what he likes and that is the rub. Listings on ebay are full of spurious claims, and the higher the catalogue value the more frequently they are encountered. I too would like a little corroborative evidence in the form of an identifiably identical 1851 die to say for certain. And if he'd spent the last couple of weeks pulling that kind of truly verifiable evidence together, he sure as hell wouldn't be leaving it to rot on his hard-drive! It would've been proudly copied and pasted into a very grand description on eBay! I see that London Coins have previously sold a few ii/i varieties and on each one part of the stop is still visible, so I think I'll give this one a miss.
