Front and back pictures of anything graded, or you think is noteworthy
A list of what’s there and a ballpark $ amount you’d like to walk away with
Step 2 - We take a look: We’ll appraise what you sent and come back with an estimate
Step 3 - Get it to us: If the number works, we meet or you ship
In Person: Sit down with us face-to-face to finalize everything
