How much could you sell a Brett Favre rookie card?

Answer 1

It depends on several factors, including the card manufacturer.

Here are the MINT condition values for all of Brett's Rookie Cards:

1991 Action Packed #21 - $15

1991 Pacific #551 - $8

1991 Pro Set #762 - $8

1991 Pro Set Platinum #290 - $8

1991 Score #611 - $8

1991 Stadium Club #94 - $50

1991 Ultra #283 - $10

1991 Ultra Update #U1 - $15

1991 Upper Deck #13 - $10

As a general rule, you will likely only be able to sell any of these cards for half of their value....on eBay, you're lucky to get 25% of their value.
