Hi
I didn't bid on this ebay (USA, where I'm located) item strong enough to win, sadly, but i think i found a 6/6 in this 1862. I sent the ebay link to Richard, of PennyVarieties, back in August, after the auction ended.
He responded with "Well spotted. Looks like a repair to the 6 as none of the other numerals are doubled. Haven't seen this one before."
It's now just past 90 days, so I don't believe I can pull up the original picture in my laptop to download thd seller's pictures vs the screenshot. Since I didn't win, I won't be able to offer much else, picture-wise (plus my filesize limit required cropping). It was a fairly pitted specimen, albeit with many details remaining on both sides. I'll see if I can post more of the full obv and rev in comments, if that may be of interest.
