The best site for buying ancient coins is definitely

It's full of different stores from the USA and Europe. Look up what kind of coin you're looking for and you should be able to find an American store that supplies it.

Denarii can vary in price depending on how detailed it is and its rarity. You can find a great denarius for a great price if you look hard enough ;)

There's a whole subreddit dedicated to this stuff too r/ancientcoins
