Question-Card Collection in Canada

Though I couldn't find a specific mention of sports cards, if you click on the following link, it should take you to the U.S. Harmonized Tariff Schedule. This section may cover what you're looking for. I would still advise contacting the U.S. Customs and Border services for a more accurate estimate.

The Chapter 49 section deals with items made of paper, and printed items, books, etc., This seems to be the most appropriate section I could find that would cover and possibly include sports cards. The Chapter 95 section includes playing cards, along with toys/games and sports related equipment and so on. So you may want to review this chapter as well for additional reference. Good luck, hope this helps.

And as Lucas said, if you can get the seller to come to you instead, it would save you the hassle of having to declare the items and possibly paying some U.S. duty/tariffs on the cards. But do maybe double check and see if you can get an advance duty estimate from U.S. Customs services first. It may end up not being that big a deal after all, or that expensive to bring sports cards back to the U.S. A lot of paper based items outlined in Chapter 49 did not appear to have any duty owed on them when bringing them into the U.S. You might get lucky after all and end up owing nothing on them. Again, good luck.
