Willie Mays - 1999 Upper Deck Century Legends #2 DIE-CUT [#/100] (Giants)

The 1-1/2 inch plastic coins, almost the same each year, came in many colors with several rare and perhaps even 1-of-1, making a "master" set almost impossible. Add in the variations and you can imagine the task.

Topps added several interesting cards in 1973 starting with card #1, a special card honoring the All-Time Home Run Leaders. Also new was the All-Time All-Star subset featuring Babe Ruth, Ty Cobb, Lou Gehrig and other all-time greats on their own special cards.

There are tons of variations (more on that later) and again issued in series with slightly scarcer semi-hi's (#397 to #528) and scarcer high #s (#529 to #660).

TOP ROOKIES were Mike Schmidt, the Phillies super-star Hall-of-Famer and the White Sox relief pitcher Goose Gossage. Not Hall-of-Famers but pretty darn good were Rookies Bob Boone and Dwight Evans.
