A 1995 Upper Deck Emmitt Smith football card number 200 has a book value of about $2.50 in near/mint -mint condition. Professionally graded cards will sell for more money than a non-graded card in the same condition. Condition is important. Common flaws with football cards include: rounded edges, creases, off centered, and faded color. Any or all flaws will devalue the card significantly.
Other than the Hawke V. Smith?
I think you're talking about Jim Brown of the Cleveland Browns who retired as the NFL's all time leading rusher. His record as since been broken first by Walter Payton and later by Emmitt Smith.
Antonio Smith
The 1990 Topps Emmitt Smith rookie card sells for $11.97. The value of a card can vary significantly depending on its condition. Smith played in the NFL for 15 seasons, rushing for 18,355 yards.
AFAIK, no.
