I only have two checks in my HOF collection, both Yankee baseball related
This one is a check from Ed Barrow to William Harridge, paying the league its share of the gate from a homestand.
Here is a Yankees payroll check to Tony Lazzeri, which was endorsed and cashed by him at the Yankee's spring training in Florida. The sig here is affected pretty badly by punches, but his sig is tough enough that I'll take it!
