A coworker of mine was trying to unload his football cards, so he sold me his entire collection for $40. The vast majority of them are from 2006.
The collection had a ton of jersey patches and autographs, but like I said, they are mostly from 2006. Its really unfortunate that draft class sucked so much. Some of these cards would be worth hundreds of dollars apiece if the players, like Vince Young and Matt Leinart, didn't bust. And he would've had a much cooler collection if he wasn't a Lions fan or if he could've kept collecting in 2007 for Megatron.
To my surprise, I found a Steve Largent auto in there, which that card itself obviously makes the whole thing worth buying.
Anyways, I added it up based on what each card is going for on ebay, and the collection is worth over $1,000, just from the rookies, autos, patches, and PSA graded Peyton Manning and Brett Favre rookie cards (both perfect 10s). If you add in all the commons, its probably worth $1,300.
