I bought 10 boxes of baseball cards for $35 each. The cost basis for each card is $.34 and there are 990 cards total. If I sell 1 card for $350, do I have tax of $0?

What about if I sell one card for $350 and sell the others for $1 total, or just throw them away?

Can I offset my $350 sale, or any other sales, by getting rid of other cards that had a cost basis higher than I got rid of them for?
