The most iconic Topps Football cards of the 2000's decade are still sought after by collectors within the hobby. Four iconic cards, including those of Adrian Peterson and Calvin Johnson, were released in Topps sets from 2006 to 2009. Despite these low PSA 9s and limited PSA 10 pop counts, these cards still appeal for collectors today. The 2008 set featured a unique design with the team name written in all capital letters and surrounded by circles. The final years of the decade saw the inclusion of future Hall of Fame rookie cards within Topps football sets, along with some that have already been enshrined in Canton.
