The scans were terrible but I'd have to disagree with the initial poster as to the notes being over-graded. Quite a few notes seem to pop up in the US that aren't in the register. Besides, if you weren't there how can you know the grade? If the notes were undergraded then price becomes moot and some looked undergraded. As rp noted, they had low estimates for the most part-DoC 1912 $5, estimate was under a grand, looked to be a stronger grade than was assigned and brought 3400 or so. I always look at the bids, if there's a lot of floor action, note is probably undergraded. Or people may have went and viewed and bid on-line if a note had lots of action and brought strong money. Person never knows unless they're there.
As for Molsons notes, not all that easy to find in better grades and I'm a buyer of those easy to find 1922 Unc's if anyone has spares.
