CANADA. Bank of Canada. 20 Dollars, 1991. BC-58b-i. Printing Error. PMG Gem Uncirculated 66 EPQ. Incomplete Back Printing Error. Only the serial numbers are visible on the back of this 1991 20 Dollar note. A dramatic and easily noticeable error that would have been identified quickly as it truly stands out and should have probably been destroyed. This example escaped, and it was meticulously cared for, now earning a Gem Uncirculated grade from the grading service.
