Mordecai Brown suffered at least one (and perhaps two) injuries as a young man, leaving him with about 1/3 of his first finger and poorly set broken bones in his second (pictures at his Wikipedia entry). It appears the "reshaped" hand gave his pitches unique torque, which he developed into one of baseball's best curves.
This 11-card set includes several big names, including Ruth and Cobb. Brown's card back only includes redemption info, with no career stats or player info. Notice how the paper-thin stock allows you to see type through both sides.
Here's the set list of players, all HOFers or known for special achievements.
- Grover Cleveland Alexander
- Three Finger Brown (Pretty sure "Fingers" should be singular)
- France Chance
- Ty Cobb
- Frankie Frisch
- Pud Galvin
- Nap Lajoie
- Babe Ruth
- Ray Schalk
- Honus Wagner
- Bill Wambsganss (only unassisted triple play in a World Series)
Value: As an obscure set of big names, prices vary quite a bit. I got this #5 for $10 from eBay, probably cheap since Brown was a redemption card for a set of Motorola data books. (See the back description.)
Fakes / reprints: They would be tricky to fake and probably hard to sell, but be aware that Motorola cards come on paper-thin stock and have a glossy finish.
