I picked up this Ted Williams PM10 pin at a flea market today and have a question on the dimensions. I measured my pin, and it is roughly 1-1/4" diameter. When I looked up this pin in the 2009 Standard Catalog of Baseball Cards (1950s-60s PM10 Baseball Player Pins - Name on top, pg 289-90), the Ted Williams pin description has the diameter at 1-3/4." Is the catalog correct? Does anyone else out there have this particular pin, and if so, what is the diameter?
