Canada’s 12 Pence Black was issued in 1851 and features a portrait of the youthful Queen Victoria. It is one of the most famous stamps in the world.
Altogether, 51,000 copies of the 12 Pence Black were printed, but due to its high denomination, only 1,450 copies were sold. The remaining unsold 49,550 copies of the stamp were taken off the market and destroyed in 1857. It is believed that about 100-150 pieces of this stamp exist today, but this is mere speculation.
In 2011, a brand new copy of the 12 Pence Black was auctioned off for US$488,900 in New York, USA.
