What do you think of
ebay lot 18151636874 ? I'd be bidding on this, but there seems to be a significant disturbance viewable in the lower left of the gum side photo. Funny thing is that it's not mentioned in the 1977 PFC. I guess it could have happened after the certificate was issued or........?
On another unrelated note, I've been on
ebay for almost 20 years now. The lot number used to be a lot more prominently displayed and in the same place. Now it seems to move around and it's almost micro printed.
