Here's another fun piece! A key date in the George V series, a 1925 Canadian 1c. Low mintage and hard to find in high grade, this one should bring at least $40 or so on Ebay.
These are graded mostly by the detail in the crown. There is a diamond shape about the middle of the crown band and that usually wears away very early. Also, there are 4 vertical pairs of pearls spaced around this same band. Usually, the pair just to the left of the diamond disappears after a very short period of circulation.
This piece, however, has all 8 pearls and the diamond. Cool!
