Does it make sense to open a Seller account for this…?

Hey there! I’m thinking about setting up a Seller account to sell fewer than 20 used books. Instead of going with Facebook, Craigslist, or OfferUp, I’m considering selling these gently used products on Amazon. I’m wondering how long it might take to sell them and whether it’s too difficult to do so. I’ve heard that Amazon’s commission is reasonable, and I like that they have a wide customer base across the country. If it turns out to be too much work, I’d rather donate the books to a local library. What do you guys think? Thanks a bunch for your input!
