I have a Nolan Ryan baseball card. What is it's value if it is not a rookie card?

Not to be mean, but look it up for yourself: New Cars, Used Cars, Blue Book Values & Car Prices - Kelley Blue Book
(you'll be able to enter how many miles, the condition, and extras & that'll be considered in the price)

WOW I'm so retarded sometimes, so sorry about my adHd... didn't see anything past the "1990" and ASSumed you were referring to a vehicle... :o

Don't worry about the rude responses. The value of your card depends on the brand, card number and condition. His rookie is 1968 topps and is available on most auction sites for approximately $150-600.
