Any issue with bring up comps when buying or selling a card?

[StraightRaceCards]

This is a good thread, and I have wondered this question

As a buyer mainly, my opinion is as long as you bring up comps respectfully and respect the dealers opinion as well, you should have no problems. If a dealer doesn’t want to work with you around comps, tell them to have a nice day and take your business elsewhere!

Or have the dealer educate you in why you should not regard comps for the specific card. There might be a good learning opportunity. Besides, people like to be heard…. Might even give you some sway on another card that the dealer has.

Like others have said, plenty of options at a show like the National

if the card is scarce, comps provide less of a foundation to stand on, but it is a good starting point.
