I just bought a 1988
Th-Cr $1000 note today that was labelled "UNC" (book value $1600), I found a small crease to the bottom right of the bill and pointed it out. The seller goes "That is why I graded it UNC and not Gem-UNC or Choice-UNC but that's my opinion, if you want I can have it professionally graded for you".
I ended up buying the note at $1175 thinking it's much closer to AU than UNC but then I got home, sat in a dark room with a sharp light on (as the book says) and without taking the bill out of the plastic, I found not one, not two, not 3, but 7 demerits.... that's right, SEVEN. The note itself is crisp, clean and sharp with no folds. But I found one too many creases and "distractions to the eye". I'm beginning to think it might be AU- or XF+. Worst comes to worst I paid a $75 premium and saved myself the trouble of running around for a $1000 note. I gave up a chance to buy a Bonin UNC at $1300 so I can buy this one at $1175 and save $125.
I will post a scan soon. If you are by any chance in the Montreal area, I'd love you to evaluate my note personally. I'll get a 2nd opinion and you'll have the amusement of grading a $1000 note
PM if interested.
Scan coming soon.... (probably later on today).
