Where to sell sports cards?

Hello! I'm located outside of Saint John. I have a bunch (hundreds maybe a thousand?) of old sports cards. I think mostly baseball cards from the 90's that were given to my family years ago but no one was interested.

I don't know anything about sports or the cards. 😅I'm assuming if any were especially valuable they wouldn't be forgotten about in my basement but I want to get rid of them.

Are there places that take such a large amount and buy in bulk or do the sorting themselves and make an offer?

Thanks
