Wow, it is possible to have variations in all those years???? How is a Cat supposed to remember all of that? Meow thought only 1992p, 1992d, 1998p,1999p and 2000p where the only issues with variations.
It's close. The gap isn't as wide as the other letter spacing because it's due to polishing. It happens a lot. You didn't hit the jackpot.
Clear gap doesn't matter because sometimes the area gets polished away at the mint, creating a gap. Best to look at the distance of the FG from the memorial.
