We do purchase professionally graded cards, however, we do not currently treat graded cards differently from non-graded cards. Any graded cards sold to us through the buy list will be opened and graded according to Card Kingdom's grading scale.


If your card has a retail value over $1,000 and you would prefer to keep it in the case, please feel free to contact our collection buyers at buyer@cardkingdom.com to see if we are interested in your specific card(s).
