I have an uncirculated 1976 $2 bill that has a smudge like error on the reverse side, lower part of door panel is undefined. On another bill, of the same kind, has a comma in the top lace-like green area on the obverse side, and has 3 small red-gold sparkle blots. Anyone with any information would be greatly appreciated. Thanks Terri
I am not a paper expert, but they just look stained to me. However, let's wait for some more experienced eyes to see your bills.
The smudge is not an error and the note is not uncirculated. As for the other errors, perhaps enlarge the area in question, or circle it, or point it out someway.
