Derek Jeter -- Game-Used Dirt For Sale

Derek Jeter fans can literally buy the DIRT he walked on -- because a sports memorabilia company is selling a collage of "dirt capsules" obtained from the 30 ballparks where #2 racked up his 3,465 hits.

We spoke to Brandon Steiner from Steiner Sports, who tells us ... his people went from stadium to stadium collecting the dirt -- which was all authenticated by Major League Baseball.

And the price ... $359.99 per collage.
