I don't own any of his cards, but I've been saying Jimmie Foxx was going to have a big price hike...for about 20 years now.
Looking at his gaudy stat lines, I feel like if Jimmie Foxx had been on the Yankees and Lou Gehrig had played on several teams like Foxx, their price structures would be reversed.
Then again, imagine Jimmie Foxx and Babe Ruth on the same team. They would have had some epic years, but they also might have had some epic parties and drinking competitions, ruining each other just a little bit at a time along the way.
