according to the nfl website you are lucky if you own one because you could sell it for up to $12,000
It depends on who signed it.
about 50 dollars if in good conditon
It is worth between $7000 and $9000 depending on the quality of the autograph.
a lot, but only if the year is 2007 a lot, but only if the year is 2007
a 2007 rookie autographed Adrian Peterson card is worth 140-450 for right now through 2007-2008 but probaly alot more in about 3 years and even more if you keep it in mint condition and wait till he retires and if he goes to the hall of fame....man i wish i was you!
2,500$ if you go to the rite person
Probably between 200 and 500 dollars depending on the buyer
If its in Mint condition its worth 300.00
