Pretty much. If you're talking about selling it locally then you also have to factor in how much star power that player has in your local market; for example, a Haloti Ngata card will probably sell for more here in Baltimore than it would in Houston.
When all else fails, list the card for five times what you think it's worth on eBay and see what kind of offers you get.
