According to Heritage Auctions it is the 1906 Philadelphia A’s, it’s a W601 Sporting Life Team Composite Pin. https://sports.ha.com/itm/baseball-c...-BidNow-071515

Looks to me from seeing the back that there was some type of silk ribbon or maybe a dated event ribbon on the bottom by seeing that bit of red silk.. One can only guess what it said!

Picked this up..

Hmmm. I grew up in Columbus. Have never heard of the Red Birds.

From Wiki:

The Columbus Red Birds were a top-level minor league baseball team that played in Columbus, Ohio, in the American Association from 1931 through 1954. The Columbus club, a member of the Association continuously since 1902, was previously known as the Columbus Senators (Columbus is the state capital). It was independently and locally owned through the 1920s.

I’m old but not THAT old! :p
