in 1851, the province of canada (approximatively ontario and quebec) was the first colony to use the chalon head on its first stamps. the april 9, 1851, two of the six first stamps bore this portrait: the 7 and a half pence green and the 12 pence black. after the adoption of the canadian dollar, one additional stamp was issued in july 1859 with the chalon head, the 12 and a half cents (with its former denomination of "six pence sterling"). like the previous series, these stamps were printed in new york.
