I have a quick question. How do you price a graded card from a company other than the big 2 (BGS & PSA)? Do you price it as if it's not graded or do you still put a premium on it, just not as much?

Today, I received a Donte Stallworth Score Inscriptions rookie Auto card that was graded Gem 10 by PGA. Ungraded, it books at $30.

If I were to trade it, would I trade it at $30?
