How much should I pay?

Selling channel guidance

Pro tip

Most card shops pay 65–70% of market value; vendors can pay up to 90% depending on the card and whether it's raw or graded.

Private collectors tend to pay full market price or slightly more — livestream marketplaces like Whatnot and in-person deals are often where you'll find the best offers.
