Hi all, I have a semi-interesting $10 with serial BL07 714 714 (TinTin-ites rejoice!). Note is in circ condition, but not too bad. The one side has these sort of "lens" shapes I think are the result of the note being stretched, but they do not appear on the other side. Is it a printing error? General damage? My experience with polymer notes is limited. Source: Me
Steve,the first two numbers indicate when the note was produced,just a bit of trivia for those that might show a little interest in notes
They look like pinch marks from where the note as come in contact with some kind of machinery, probably a note counter or a vending machine. I'd say that note has been used a fair bit, but in relatively clean environments - it looks scuffed, but not dirty.
