On U.S. sites I'm accustomed to U.S. Silver Eagles having the highest premium. Maple leafs are usually significantly cheaper, but usually cost more than Krugerrands, Kangaroos, Brittanias and Philharmonics. Looking over S.D. Bullion's site, I see Silver Eagles are only $0.10 (U.S.) more than Maple Leafs, and Kangaroos are $0.10 more than Silver Eagles. What's going on? I had been stacking Maple Leafs because they were significantly less than Silver Eagles and later switched to Kangaroos when the premiums on Maple Leafs went up in late summer. Maybe it's a supply issue. I can still get Brittanias cheaper than most other coins. Thoughts?
