Freshly back from SABR50 in Baltimore a number of questions from attendees are fresh in my mind. Perhaps the question most frequently asked pertained to assessing the value of a collection. Sometimes I’d ask for a description of the collection in question, and a typical reply might be “several boxes of cards from the 50s and 60s including Mickey Mantle.”
I’ll use this article to acquaint readers, particularly those who aren’t active buyers and sellers, with the main variables at play in putting a price tag on, say, a 1950s Mickey Mantle.
Which Mantle?
Without a doubt, not all Mantles were created equal. Head and shoulders above all others, at least as far as his standard Topps and Bowman issues are concerned, is the 1952 Topps card.

Mantle’s 1951 Bowman card, which doubles as the Mick’s rookie card, also carries a substantial premium, though perhaps counterintuitively a much smaller one than the aforementioned Topps card.

In general, not as a hard and fast rule but as a trend, older cards are worth more, and rookie cards in particular are worth the most. Though we have already seen an exception, it’s true much more often than it’s not. The graph below illustrates this for a hypothetical star player whose first card was in 1960. Note the significant drop-off from 1960 to 1961 and the overall decreasing trend across the decade. You might also recognize a significant drop-off between 1961 and 1962. This too is a thing as second year cards tend to carry a premium, though not nearly as much as first year (or “rookie”) cards.

Now, here is an actual graph for Mickey Mantle’s 1950s baseball cards. As we will soon see, the condition of the card plays an outsized role in valuation, so at the moment we will pretend all cards in the graph are of equal condition. (For those keeping score at home I’ll assume PSA 5, but don’t worry if you don’t know what that is.)

One thing you’ll note right away are the two sets of bars used, one blue and one orange. These correspond to the two major producers of baseball cards in the 1950s, Bowman and Topps. Bowman produced cards of Mickey Mantle annually from his first card in 1951 through the company’s demise following the 1955 season. Topps, meanwhile, issued Mantle cards in 1952 and 1953 but was forced into a two-year hiatus by rival Bowman who had Mick locked into an exclusive deal for the 1954 and 1955 seasons.
If you glance at the graph, one color at a time, you see that each color follows the general trend of the hypothetical graph presented earlier. Whether blue or orange, a downward pattern is unmistakable, and significant premiums are attached to the first of the bars.
So what was the purpose of all this? Mainly, I wanted to reinforce the idea that the value of a Mantle depends a lot on which Mantle. This weekend a 1952 Topps Mantle may make headlines by selling in the neighborhood of $10 million. This will no doubt cause some to wonder if the box of cards in their attic might produce its own seven-digit payday. Of course, as the graph shows, most Mantle cards (all but one, really!) are worth nowhere near that.
Before heading into our promised discussion of condition, I’ll share three more bits of information on the which Mantle front.
- Particularly for cards produced before 1974, you will sometimes see exceptions to the monotonicity of the Value vs Year graph due to a “high numbers” effect. In many older sets, the cards at the end of the set were sold in smaller quantities, hence have greater scarcity. A famous example is the 1967 Topps Brooks Robinson, which is worth far more than any of his other 1960s Topps standard issues. (And yes, in case you’re wondering, Mickey Mantle had a “high number” card in the 1952 Topps set.)
- Some players, especially stars, can have more than one card in a set. For example, Mickey Mantle has all three of these cards in the 1958 Topps set (and some might add the Yankees team card as well). Nearly always, the base (regular) card is worth more than the extras, in this case a World Series card with Hank Aaron and an All-Star card.

- I’ve limited discussion thus far to cards from the major producers. However, the baseball card ecosystem is typically far larger than that. In 1954 alone, Mickey Mantle also had a dog food card, a potato chips card, a wiener card, as well as a couple others. It’s difficult to attach a general rule to the pricing on such cards. On one hand, they are generally less sought after by most collectors. On the other hand, some can be quite scarce. Thus there is some tug on their value in both directions, reduced demand pulling prices downward and reduced supply pulling prices upward.
In What Condition?
Even when I was a young collector in the late 1970s I knew cards with sharp corners and no creases were more valuable than ones you could practically roll along a table. This didn’t stop me from keeping my favorite cards in my pants pockets, but then again was I ever planning to sell them?
At any rate, the same is true today, but the premium on “high grade” vintage cardboard has only increased, in my eyes past the point of absurdity. Nowadays, much of the dealings in the Hobby’s upper stratosphere transpires with cards that have been commercially (the implication being professionally and objectively) graded by companies like PSA, SGC, and Beckett. While these companies certainly have their share of misses, the logic is that a well trained third party grader is more trustworthy than the card’s owner, who naturally stands to profit (at least in the short term) by over-stating a card’s condition.
Most grading is done on a numerical scale from 1-10, but the scale is decidedly non-linear. For example, here is a graph showing the value of the 1959 Topps Mickey Mantle card across its range of conditions. (Source: PSA, August 24, 2022.)

There have been no recent sales of the card with a grade of 10 and in fact only one such card has ever been graded by PSA. As such, there is no bar on the graph at 10, but you might have some fun guessing what such a card might go for based on the graph as shown. Half a million?!
Before proceeding I’ll show the same graph for grades 1-8 only, since the current graph’s very tall bar at 9 tends to dwarf all else.

The reason I’ve shared these graphs is to show just how much grade impacts value. For this particular card, a card graded 9 is worth more than 500 times as much as a card graded 1. Let’s unpack this a bit more.
Perhaps a friend lets you know that he just sold one of his 1950s Mickey Mantles for $1000, and—lo and behold—you have that very same card. Your copy might be worth $100 or it might be worth $10,000, maybe even a lot more than that! The point is, condition doesn’t just attach a premium; right or wrong, it creates a 500x (or more) differential in value, even when we’re talking about the exact same card!
I just illustrated the non-linearity of condition with respect to value. Separate from any discussion of market value, I’ll add my opinion that condition is also non-linear with respect to appearance. This may sound contradictory at first since you may view condition and appearance as synonyms, i.e., how the card presents. Either way, let’s take a look.
Here is the 1959 Topps Mickey Mantle card in grades 9, 8, and 7 respectively. At first glance, you would not be wrong to imagine the three cards identical. If anything, you might even dock the “9” for what looks like a very small stain below the O in OUTFIELD as well as some faint discoloration above the mickey mantle name.

At any rate, if we presume no error or subjectivity in the grading, we can only assume that there are important distinctions not necessarily evident to the naked eye (or, in fairness, on the backs of the cards). Perhaps the “8” has some microscopic corner ding, for example. Still, the larger point is that a 7, 8, and 9 all look almost exactly the same. (Notably, the card on the left sold for more than 30 times the card on the right!)
While I’ve illustrated my point using three cards, to my own eye the top six slots on the grading scale, i.e., grades of 5-10, all look about the same. Don’t get me wrong. If you look hard enough, I bet you can figure out which of these Mantle cards is a “10” and which is a “5” but I’ll still paraphrase Maya Angelou and say they “are more alike, my friends, than they are unalike.”


Back to value for a second, one of the two cards pictured sold recently for $1600. The other, were it to hit the market today, would likely fetch upwards of $500,000. 🤷🏻♂️
Sometimes someone sends me a picture of a card they took with their phone and asks what I think it’s worth. I hope the two Mantle cards illustrate the difficulty of providing such an assessment, particularly when cards are in really nice shape, hence differences in grades reflect only tiny distinctions but gigantic pricing differences.
For completeness, I’ll illustrate the lower end of the scale, where distinctions are much more notable, though still not always evident.

Though I’ve used graded cards to illustrate the hypersensitivity of price to condition, there are again some notes to offer.
- Some cards receive half-grades (e.g., 3.5). Pricing for half grades is about what you’d expect.
- Many sellers, even when a third-party grade has been assigned, will hope to realize a nicer sale by claiming their card is “under-graded” or “the nicest 3 you’ll ever see.” I can definitely say that grades being equal, some cards look better than others. Ultimately though, the buyer should be the judge of this rather than simply take the seller’s claim at face value.
- Some cards receive non-numerical grades, the most common being “Authentic,” which usually is not as good as it sounds, and the most dreaded being “Counterfeit!”
Last but not least, most cards bought and sold are not graded. (Sometimes the term “raw” is used.) Here there is a greater risk associated with fakes, but the good news is that most of the folks out there buying vintage collections are able to tell real from bogus. As such, if you’re thinking about selling your childhood collection of 1950s cardboard, you need not panic that the only way to get anything for it is to spend tens of thousands of dollars having it graded first.
That said, if you are selling online to someone who can’t handle the cards directly, you may well experience a lower sales price based on buyer uncertainty over authenticity. A return policy and clear images mitigate this, but many online buyers will still attach risk to your cards and lower their offers accordingly.
Conclusion
Though it seems ridiculous, the value of a 1950s Mickey Mantle can be anywhere from about $10 to $10 million. Two factors that make a very, very big difference are which card you have an what condition it’s in. These certainly aren’t the only factors, but they more than suffice to make the point, which is that it is exceedingly difficult to assess the value of a vintage card or collection without spending some real time with it.
So what’s the value of that box of 1950s and 60s baseball cards from your childhood, the one you’re positive has a Mantle or two? There’s only one real answer, and it’s an incredibly unsatisfying one: it depends…and almost comically so!
