Team signed baseballs were the thing well before single-signed balls exploded on the market.
What is a "Team Signed Baseball" ???
Simple answer: A ball with XXX signatures of a certain team for a certain year. What is difficult is the XXX. Baseball tons of roster moves make it nearly impossible to "Get Them All".

Generally, team signed baseballs from early 1900's had 10 to 15 signatures, the 1940's that jumped to 18 to 25. Joyce Sports Research Collection (Notre Dame) says "signatures must include only members of a specific team from a specific year, and there must be some approximation of completeness."

Not concrete but to me a "team ball" MUST have ALL the team's STARS (unless a rookie or in season trade) and in today's market at least 20, preferably more, and the manager.

Determining Age of Team Signed Balls
"Official" league balls have stamped signatures of current league presidents on the "sweet spot". Starting 1934/1935 balls were produced by Spalding (NL) and Reach (AL). Rawlings took over in 1977/78. Have a possible team roster at hand, ESPN & baseball-reference.com have great sites), decipher a few signatures then solve the puzzle.

2 reasons auctions are popular way to sell vintage sports cards.

ASSUMPTIONS:

#2) You have mostly late 80's & 90's "junk"
Consider donating the "junk" and keep better stuff to sell later. Tax deduction was based on LESSER of "what-it-cost" & "What-it's-Worth". For "What-it's-Worth", I use Beckett which can be higher than what you paid. Check with your tax guy.

How long have sports cards been around ? (part 2)

The first important and mainstream basketball set was issued by Bowman in 1948. Other than a Topps set in 1957-58 and a 1961-62 Fleer set, there were no mainstream basketball sets issued until Topps started producing yearly sets beginning with their 1969-70 set featuring the rookie card of Kareem Abdul-Jabbar, who then went under the name of Lew Alcindor.

In hockey, there were a few sets issued in the 1910's and while O-Pee-Chee issued some sets in the 1930's, the real modern sets began in 1951 with the itroduction of Parkhurst's first set.

In racing, while cards go back as far as the early Indy car days of 1911, modern racing sets began in 1988 with the issues released by MAXX.
