After reading the descriptions describing a reverse proof, I went through my coins & found that I already had one; not an ASE but a Canadian Mint 2002 Proof coin. Are all the Canadian Mint coins Reverse Proof? I still can't find where the reverse proof ASEs are minted or how to subscribe for them from the Mint. I'm not so much interested in the coins themselves, but in the seemingly lack of info available about them...
the ASE reverse proof was only available once as a part of the 20th anniversary Silver Set in 2006. The set sold out at $100 issue and the coin sells for quite a premium, selling in the $250 range on the secondary market.
They also struck a reverse Gold Eagle in 2006. Those are selling for $3300.00 in Reverse PF69 and $4800.00 in reverse PF70, graded. Bruce
I am assuming you are talking about the silver maple leafs. The Royal Candian mint has been making normal Unc maple leafs since 1998 and also feature a proof verision. The RCM has also been making the "reverse proof" version of their maple leaf coins since 1998 which feature privy marks (1998 had a RCMP mark). The mint does not technically call the reverse proofs however... but since the frosted and polished regions are inverted compared to the proof coins, I guess they qualify. A link to more info: http://en.wikipedia.org/wiki/Canadian_Silver_Maple_Leaf#Privy_Mark_Silver_Maple_Leaf The 2006 ASE reverse proof was minted once only (no subscriptions) as a part of the 250,000 20th anniversary sets. These have not been avaiable from the US mint since late 2006...
