In December 1953, Topps cut Willie Mays a check for a whopping $50 to appear in their 1954 baseball card set—less than what a torn copy of his card is worth today.

Here’s the item description from Mastro’s March 2000 catalog, in which it appeared as lot 663:
In late 1953, Topps Chewing Gum and Willie Mays agreed on the terms of a 1954 baseball card contract with an option for 1955. Mays would receive a lusty $50 for the use of his picture on the 1954 Topps baseball issue (May we note that today, a ’54 Topps May, torn in half, is worth more than this original compensation). We have here for your collecting pleasure that very check. The December 17, 1953 check from Topps Chewing Gum Incorporated is made out to William Howard Mays and signed on the back “William H. Mays Jr” in fountain ink. Sarah Mays, Willie’s mother, has also signed on the back, including her address in Fairfield, Alabama. This unique check shows fold lines and a paper loss on the left border, giving it a technical grade at about Very Good; however, it has a terrific full name autograph and provides that historic link of Willie Mays with Topps. A magnificent relic realized through pitiful exploitation. Kevin Keating and James Spence LOA’s.
Minimum Big $300
Here’s the back of the check with the terms and Mays’ (and his mother’s) endorsement:

Happy collecting!
