The New York Yankees home jersey from Lou Gehrig's last dominant season as a big leaguer is on the auction block ... and it's expected to sell for a whopping $3-4 MILLION!
1937 was the last time Gehrig would play a season unaffected by ALS -- the progressive, neurological disease that ultimately took his life in 1941 -- and was he ever great.
The Iron Horse put up ridiculous numbers, blasting 37 home runs and driving in 159 runs, all while batting .351. Gehrig only struck out 49 times (for reference, last year's league leader struck out 221 times).
