I have a 1999 Coloured Gold Maple Leaf Set, 5 GML's, for the 20th Anniversary of the GML. I'm told that there is a reference to them in the Charlton Standard Catalogue of Canadian Coins, 60th Edition, p.440.
I was once told by the Mint that these coins were not coloured at the Canadian Mint, but Charlton seems to have something else. Any chance one of you can scan the page for me? I'd like to sell the set, but need to know more about them.
