12. Baseball signed by Joe DiMaggio & Marilyn Monroe – Sold for: $191,200
Marilyn Monroe and Joe DiMaggio married in 1954, attracting widespread media attention because they were both so famous in their respective fields, and helping this baseball to make the most expensive signed merchandise list.
This baseball is the only known item in the world which is signed by both Monroe and DiMaggio, but was actually signed in 1961 after their divorce and one year before Marilyn Monroe died. The buyer was apparently an avid fan of both Monroe and DiMaggio.
