Let us go back in Canada's historical time to the yesteryear 1967. 1967 was the Centennial (100th) year of their Confederation. To help in celebration of the occasion a commemorative Silver Dollar was authorized to be struck. The obverse of the Dollar would bear Arnold Machin's rendition of Queen Elizabeth II. The reverse was to bear the image of a flying goose (1967 only) with the denomination (DOLLAR) above and the Centennial dates (1867-1967) below. Alex Colville designed the reverse. The resulting coin measures out to a crown-sized 36mm, weighs 23.3276 grams and contains 0.6000 ounce of silver. 6,767,496 were struck for circulation. Heres two photos of that coin courtesy of The Coin Page: OBVERSE: http://www.coinpage.com/coin-image-6392.html REVERSE (non error): http://www.coinpage.com/coin-image-6393.html http://www.coinarchives.com/w/lotviewer.php?LotID=1004477&AucID=931&Lot=8108&Val=37d08396f0d5d5180ac1e7d22bea0f8c Folowing is a photo showing an error on a 1967 Canadian Centennial Silver Dollar which, somehow, was released bearing a doubled reverse (Coin Achives photo): http://www.coinarchives.com/w/lotviewer.php?LotID=1004477&AucID=931&Lot=8108&Val=37d08396f0d5d5180ac1e7d22bea0f8c Hope you enjoyed learning about this error...

I remember seeing that in coin magazines that I bought in 1967 and 68. It was called the "diving goose" and it had a pretty hefty price tag of more than $200, if I remember correctly. But by 1969, it seems to have disappeared from the spotlight.
I wish I had been able to keep my coin magazines from the 1967-68 era. As it were, most of them fell victim to "spring cleaning". Somehow, I was able to salvage an August 1969 issue of Coinage magazine, and I have not found a single mention of a "diving goose" in that issue. But they were being promoted in the previous year's magazines.
