The days of when Upper Deck ruled the high-end NFL trading card market.
I purchased this 6 card retail pack of 2009 Upper Deck SP Threads Football for $1.

The main hit in that series are the autographed and/or memorabilia Matthew Stafford rookie cards, that's still very easy to sell for a decent amount.
Base Cards

38 - Frank Gore

Gore rushed a career high 10 touchdowns in the 2009 season. He might have rushed even more touchdowns if he didn't suffer from a two-week injury.

On April 2, 2009, Cutler was traded to the Chicago bears where he continues to play for.

Tomlinson retired after rushing 13,684 yards and 145 touchdowns.

65 - Lofa Tatupu

Tatupu played his worst season in 2009.

Some experts expected Brady to be rusty at the start of the 2009 season due to a season long 2008 injury -- but that wasn't the case!

Gonzalez retired in 2013 with 15,127 yards and 111 touchdowns.
