Huh, none of these coins are in general use in any country because it would make no sense (their facial value is always largely below their metal value, which is basically constantly appreciating). As a French person I have never seen 20 francs coins in circulation either, and I wouldn't by my baguette with one, but they are still obviously not a "scam", even if their actual value doesn't match their face value. I mean, I should know since I actually buy them, manipulate them, and use them for their gold content.

The page you linked is quite unlikely to be a scam (except that it sells the coin for quite a premium, compared to what I can get at home like say https://www.argentorshop.be/en/gold-coin-chinese-panda-30-gr... in Belgium).

I think you don't understand how these gold coins work, honestly I don't claim I really understand why central banks produce them either, but they do exist and they seem like a convenient way to invest in real gold (and here comes my initial remark: but why choose the ones that sell for a premium as compared to the ones that sell just for their weight in gold, that I don't understand).

You can get more information on the Chinese Gold Panda coins on Wikipedia if you like: https://en.wikipedia.org/wiki/Chinese_Gold_Panda
