Paul Konerko signed baseball; high school 1994
 

Long before the White Sox, in 1994 at a Phelps Dodge company picnic, Paul Konerko signed 36 baseballs for prizes. If I remember correctly at the time, Konerko was in the top 100 high-school baseball players (he was a catcher). His father, Hank, was a senior executive at Phelps Dodge. Does anyone have an estimated value?

based on eBay sales, Konerko single signed baseballs sell for about $20 each (other than on 2005 WS baseballs)

Thanks for the information.
