Well, as a Canadian-American, I have collected some Canadian coins, but not in depth. One thing I found interesting is the 1991 25 cent coins? Why? Because only 459,000 were minted that year because of a strike at the mint. I have four of them in proof and the proof had a mintage of around 133,000 for the 459,000 mintage I have two sent to me. I also like the Canadian Ottawa Sovereign Gold Coin, but don't have that. It does not have a high mintage and is worth collecting. Basil
