My initial thought was AU. But then I amended that thought by adding "by American grading standards". Canadian standards tend to be a bit tougher. So I would probably expect an XF from them.
Well done. I wouldn't have known the problem. But since you pointed it out, I vaguely remember seeing serial numbers in that range being something "different".
I suggest that you don't use the "PCGS guide price" as your guide. The Greysheet is a much more accurate guide to prices. It's pricy but you don't need a monthly subscription. I get it 4 times a year but 1 or 2 a year is plenty good.
And then there is always spending the time searching auction results. eBay is the easiest but the other auction houses are more accurate as long as you take into account their buyer's premium.
I have two 1811 ½¢ slabbed by PCGS. One is without a die crack; the other is a 4-star cud. I may look for one with a pre-cud die crack. The 2-star cud variety is too expensive.
