To the left of the 8 on this Great Britain Trade Dollar, there appears to be a slight impression of an 8. It doesn't look to be MD. It's as if the die engraver accidentally lightly punched the 8 in the wrong spot, shifted to the right of the coin (left of the die), then finished the 8. It's not listed as a double die variety by NGC.
I can see what you are talking about. Would you be able to provide a whole-coin shot? I'm not familiar with the minting process of GB so I wouldn't be qualified to talk on that potential error, I just think your coin is going to look very nice.
I won't be able to for this coin for now... and I'm unable to post any pictures at the moment since my SD card is fried.
Yeah, I agree. Possible 1908/8, but not a doubled die. You would see doubling on all the digits to the same extent as on the 8 if it were a doubled die.
I do not believe it is a DD nor a repunched due to the shape, it appears to be die deterioration to me, even with the other numbers of the date.
The correct terminology is Doubled Die not Double - I want to share this webpage with you - https://en.wikipedia.org/wiki/Doubled_die quote - "Note that the proper terminology for this occurrence includes the letter 'd' at the end of the first word, hence "doubled die". The term "double die" without the first word ending in 'd' is not proper numismatic terminology." closed quote
Come to think of it, "double die" would only make sense if there were two different dies used, like a doubled denomination coin.
