Cater (b. 1940) played in the majors from 1964 to 1975 for the Phillies, White Sox, A's (KC and Oakland), Yankees, Red Sox and Cardinals. He had 1,229 hits, 66 home runs and a .276 batting average. He finished 19th in the 1968 AL MVP race.
I mailed to Cater on November 23 and got the cards back on December 4, for an 11-day TAT. I paid his fee of $5/card.
