I've added another oddball to the Billy Williams PSA collection
This is the third different pin from 1969. It comes from a set of 20 pins put out by Kelly's potato chips. The company is from central Illinois and the set skews heavily towards players from Chicago or St. Louis. Twelve of the 20 are Cubs, Sox, or Cardinals.
The pins come in two colors. The American League players have a red pin while the NL players get blue. Kelly's went out of business in the mid-90's, but the brand name lives on with these pins.
The pin now gives me 98 of the 127 items on the PSA list, good for 77%.
Here's a look at all 98.
