As a kid I loved shopping with mom hoping to find my next favorite food - the one with baseball cards !!! In 1955,1959 & 1960, kids could enjoy hot dogs with their cards thanks to Armour's coins in 1955, 1959 & 1960.

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.

See sportscollectorsdaily for great 1955,1959 & 1960 Armour baseball coins article.

1960 & 1961 Fleer baseball card sets of old-timers like Babe Ruth bombed. Kids wanted Willie Mays & Mickey Mantle. Topps had rights to baseball cards & gum so Fleer tried something new ... COOKIES !!!
Cherry flavored cookies with 1963 baseball cards.
1963 Fleer baseball card set was cut short at 66 cards & checklist by Topps lawsuit. But what 66 cards! Attractive & packed: Clemente,Koufax... & 2 very scare Short Prints.
Maury Wills 'rookie' card is a story. Majors in 1959, quickly superstar. But 1963 for rookie ??? In 1959 Topps deemed Wills NOT WORTHY.

Wills was upset. After 1962 MVP, Topps came knocking but he said "NO!". Finally, 1967, Wills first Topps & most costly card. Note: 1961 Post Cereal card, years BEFORE 'official' rookie. He also photo-bombed a 1960 Topps card.

Disclaimer: Above mostly true - but Wills has said "no feud".
