This is a Canada 1900 Queen Victoria Stamp. It is S.G. 165, the 20 Cent Olive Green!
This one is off-center on the upper left, and in fine to very fine condition. It's also Mint with Original Gum and a hinge remaining. Even so, this is a RARE stamp!
This is valued at L325 in the Stanley Gibbons Catalogue.
