COMC offers limited info for most users on past sales. You can look at the bar chart on the left of the screen to see volume sold broken down by quarter. But for actual prices you need to acquire some sort of "history points" that you can buy or earn through selling or something.
Good tutorial, Patrick. Is there a way to check recent sales on COMC? I'm familiar with the "sold out" filter, but that only shows items no longer available.
Switching gears, hopefully you're putting together a "quarantine edition" of your Top 10 pickups of 2020. Those are fun to see!
They do look bigger, don't they. I think the white space throws us all off though. From what I've heard from credible sources, however, they are exactly the same dimension as those made by PSA.Those slabs look awful. There is no reason the flip should be half the size of the card.
