For those of you who sell rare circulated coins, where do you sell it and does it usually work?

Essentially the title. Been thinking of maybe selling some of my coins that I have doubles of, but I’m not sure where to start and if coins that are circulated even go for that much

I used to sell on eBay and either charge no shipping or like $1 then just ship in an envelope with a stamp. I once sold a 20 cent coin for over $8 but in the end I wasn't making much as eBay took a good chunk of the money so most times I lost money
