4 Forgotten and Undervalued Vintage Baseball Card Sets

In this story:
Most vintage collectors end up chasing the same cards. Topps and Bowman sets, especially from the 1950s, dominate the vintage baseball card hobby. Their popularity is well-earned, as these iconic, mainstream sets remain recognizable even to those who only collect casually.
These popular vintage cards have constant visibility, high populations, and well-established price ranges. Because so many collectors are watching them, finding an undervalued gem is a challenge. On the other hand, several vintage sets remain largely ignored, offering savvy collectors a chance to buy undervalued sleeper cards before the rest of the hobby catches on.

While some collectors insist that "it’s only a card if it came from a pack," many of the most exciting vintage cards were actually distributed in vending machines, cereal boxes, tobacco packs, or even dog food packaging. Even Topps experimented with some unconventional sets in an effort to be creative. Here are four of the most undervalued and overlooked sets from the vintage era.
1. 1934–36 Diamond Stars Set

Most Expensive Card: 1934 Diamond Stars Lefty Grove #1 PSA 8 - $28,800
Undervalued Card: Bill Dickey 1934 Diamond Stars #11 PSA 5-$515 (214 Total Population)
Mainstream Comparison: Bill Dickey 1933 Goudey #19 PSA 5- $1,500 (1,257 Total Population)
Set Overview: Produced by the National Chicle Gum Company to rival the popular Goudey cards, this 108-card set is a favorite among vintage collectors for its iconic "Art Deco" design. (The original paintings used for the designs have fetched five-figures.) The set is overshadowed in large part because of the absence of Babe Ruth and Lou Gehrig, but it still includes an impressive roster of Hall of Famers, including Lefty Grove, Rogers Hornsby, Mel Ott, Hank Greenberg, Jimmie Foxx, and Bill Dickey.
2. 1954 Red Heart (Dog Food) Set

Most Expensive Card: 1954 Red Heart Mickey Mantle PSA 9 - $35,990
Undervalued Card: 1954 Red Heart Warren Spahn PSA 5 - $288 (895 Total Population)
Mainstream Comparison: 1949 Bowman Warren Spahn PSA 5- $436 (1,522 Total Population)
Set Overview: 1954 Red Heart was an “oddball” set of cards tied to a dog food promotion, distributed regionally by the John Morrell Company. The cards were originally available via a mail-in offer for two dog food labels and 10 cents. The set is famous for having an iconic looking Mantle card that is highly sought after. It is also known for its Stan Musial, who was absent from both the 1954 Topps and Bowman sets due to a contract dispute. Musial was the advertising spokesman for Red Heart.
3. 1952 Red Man Tobacco Set

Most Expensive Card: 1952 Red Man Ted Williams #23 PSA 8.5 - $12,535
Undervalued Card: 1952 Red Man Willie Mays PSA 4 - $350 (396 Total Population)
Mainstream Comparison: 1952 Topps Willie Mays PSA 4 - $17,805 (4,703 Total Population)
Set Overview: The 1952 Red Man Tobacco set was the first national tobacco-related baseball card issue since 1912. The set featured 52 oversized cards that were originally distributed inside clear plastic pouches attached to the outside of Red Man chewing tobacco. Each card included a tab, which was meant to be cut off and mailed in (50 tabs) to redeem for a baseball hat. Because most tabs were removed for redemption, cards with the tabs still attached are significantly rarer and command a premium.
4. 1964 Topps Stand-Up Set

Most Expensive Card: 1964 Topps Stand-Up Mickey Mantle PSA 9 - $21,350
Undervalued Card: 1964 Topps Stand-Up Brooks Robinson PSA 8 - $337.50 (521Total Population)
Mainstream Comparison: 1967 Topps Brooks Robinson PSA 8- $1,149 (2,915 Total Population)
Set Overview: Unlike the standard 1964 Topps set which contains 587 cards, the 77-card “Stand-Up” set was designed for kids to punch out and display (the player inside the card could stand upright). Because these cards were specifically designed to be handled and folded, finding them in high-grade, "un-punched" condition is extremely difficult.
