It depends on several factors... 1 demand of the player(local sport teams are best) but popular players too. 2 quality of the cards. Autos, game used, and rookie cards sell best but he will buy base cards and inserts if they're the right players. 3 condition and years of the cards. Unfortunately most baseball cards from 1986 to about 2000 dont have much value or demand. Hope this was helpful.
Yes they buy any kind of sports cards.
