A game-worn, no. 28 Sandy Koufax Brooklyn Dodgers jersey, signed by greatest left-handed pitcher of all time, sold for $80,393 on Lelands.com. Koufax's original no. 32 was removed from the jersey when it was sent down to the minors.
Here's the item's description from Lelands:
We can count the number of Brooklyn Dodger Koufax gamers that we know of on two fingers... This white home jersey has the all-original "Dodgers" across the front in blue felt. The Rawlings "Hall of Fame" size 44 tagging is on the front left tail, along with a chain stitched "Koufax 57" underneath the tag. Inside the front tail are the washing instructions and a "Set 1 1957" flag tag. The original number "32" was removed from the jersey when it was sent down to the minors. It has been replaced by the number "28" on the front and back. When held to the light, the outline of the original "32" still can be seen. The lefty pitcher Koufax signed his name on the front of the jersey in blue Sharpie. The signature is graded an 8/10. The jersey shows very nice use with no holes or tears from this living legend.This is only one of two jerseys known to have been worn in a game by the Hall of Fame pitcher.

This is one beautiful jersey, and in my opinion, worth every penny.
