I have a number of 1oz Canadian Maples, and I am looking to diversify a little into Gold coins. My first opportunity is with a $20 1967 Canadian Gold Proof. I am trying to figure a fair trade, given the lower quality of the 1967 coin vs. current maples, the fact that the 1967 is not part of the larger 'collectable' set, and the fact that it seems like you can get those coins at melt price, while the silve maples are always at a premium. Any suggestions on a fair trade or how to comparatively value the two coins? Spot for spot, it looks to be in the 27-28 Maples range. Thanks for any advice!
