I think it's a work out S for San Francisco. Small possibility it could be an O? Anyone able to confirm? I know it's not the best quality, but I like it :). I also was not the one who tried to clean it. I got it years ago and it's been in its bag\case since then, except for today when I wanted to check it out under the microscope.
My oldest currency. Pretty cool, not the best condition, but cool to see.
5 in a row, then 2 in a row.
Nothing else fancy about them. Not a huge value. Just cool to see. (To me at least)
I don't think they're mis-prints as I checked multiple and they all look the same.
Put North Dakota in there to show a normal T is possible.
Update: it's because that's how it is on the monument. Leaving this thread open though as y'all are funny.
Thanks for the responses!
Just so satisfying to play. Not too difficult. Just a crash into things and enjoy game.
