The story on this card
Bollo's card arrives the year he broke into the majors, debuting for the White Sox on May 9, 1965 and pitching in relief for the rest of the season. This high number comes from the final series, inside the short-print zone, and shares its Rookie Stars design with fellow White Sox arm Bob Locker, pairing two first-year pitchers from the same club on one card. It stands as Bollo's recognized rookie card. A hard-throwing right-hander from Detroit who pitched out of the White Sox bullpen in the mid-1960s, working in relief far more often than he started.
1965 Topps #541, a high number in the seventh print series inside the short-print zone, is a Rookie Stars card shared with fellow White Sox arm Greg Bollo. It marks Locker's rookie card. He made his big-league debut that April in Baltimore and settled into the Chicago bullpen behind knuckleballers Hoyt Wilhelm and Eddie Fisher, finishing his first season 5-2 with a 3.15 ERA over 91.1 innings. A sinkerballing reliever from Iowa who anchored bullpens for the White Sox, Pilots, Brewers, Athletics and Cubs, and pitched for Oakland's 1972 World Series champions.

It is card #541 of the 598-card 1965 Topps Baseball set, picturing Greg Bollo and Bob Locker. This is one of the 55 Rookie Stars cards in the 1965 Topps set, each picturing two to four young players - 126 players in all - under a team banner, except #577 and #581, which carry American League and National League banners over players from three clubs.

Is 1965 Topps #541 a scarce card?
It is a high number card from the seventh and last series, #507-598. Unlike most 1960s Topps sets the 1965 highs are not scarce as a run - the premium sits on the short-printed cards inside #523-598. It is also a short-print zone card. Forty-four of the 76 cards in #523-598 were short-printed; #507-522 was not. The zone is stated as a range because the catalogs disagree on exactly which cards, so no single card is marked.
How many cards are in the 1965 Topps Baseball set?
598 cards, tracked as 600 collectible states. Numbers run from 1 to 598 with no gaps and no printed-number collisions, and two checklist cards - #79 and #508 - carry catalogued print variations that the master set counts separately.
