This is bullion, mintage numbers are not that important in my opinion. I don't think the US Mint has announced final mintage numbers for these. You can go to the production page of the US Mint to see how many they have made so far this year. The US Mint will soon be switching to make the 2023s if they haven't already.
Premiums for the buffaloes are more than for the gold eagles. The US Mint makes a lot more gold eagles than buffaloes I assume because of popularity. 1 ounce buffaloes are .999 gold, the 1 oz gold eagles are about .91% gold, both have one full ounce of gold. If you go to ebay sold listings you can see how much they are going for currently.
@livingwater... Thanks. That's about what I knew and you've confirmed for me my thinking. Last year, when in the U.S. I noticed some attention to mintage numbers in their AGEs but I haven't handled a buffalo before. Thanks again.
I think you will find the premiums for US Silver Eagles, Gold Eagles, and Buffalos to be a bit higher than for other forms of the same bullion. The premium you quote is a little higher than I would have to pay in the USA. I expect gold to continue to decline as long as the dollar advances. In my opinion, better to hold currency in dollars now until the dollar ends its run. I do think AU will rapidly appreciate in the not too distant future.
