I thought this was an interesting video, as it discusses card population reports, not generally, but how they can change over time and, most importantly, what those changes tell you about the true scarcity of a card. The current PSA backlog (7.2 million) also plays into how to think about population reports and what they could eventually be.

Hobby Thoughts: The Effect of Seasonality on Vintage Baseball Card Values, Continued
As I mentioned in the newsletter two weeks ago, I thought I should see how HOF baseball player indexes moved from 2024 to 2025, both during the offseason and in-season, relative to how they moved from 2025 to 2026. I wanted to test my theory about the overall price increases in the card market since February of this year heavily influencing the player index increases during the baseball season.
I looked at the period from October 30, 2024, to October 30, 2025 (i.e., the end of the 2025 MLB season), breaking the year up before and after March 27, 2025, the beginning of the 2025 season, using the Card Ladder indexes.

To see how the rest performed, you can see the full 58-player results here
(I’ve come to realize that, in my initial research for 2025 to 2026, I mistakenly counted the Baseball and Vintage indexes as player indexes, which is why my count two weeks ago was 60 players instead of 58, and that mistake also affected the numbers used in my analysis. Lesson learned, and apologies for that mistake.)
Methodology:
The players chosen were all Hall of Famers, had rookie cards between 1940 and 1980, and had Card Ladder player indexes
Each player index was given both date ranges to determine the percentage change in the value of the index
Not all Hall of Fame players have player indexes, as each index has cards Card Ladder determines eligible based on sales activity (more info here), and there is a WIDE range of the number of cards (as an example, Don Drysdale has one card, while Mickey Mantle has 544).
Like the 2025 to 2026 range, there was a separation before and during the baseball season, with 44 of the 58 player indexes increasing during the season, while 36 player indexes increased during the offseason.
There were also differences, though.
Fewer player indexes increased during both the offseason and in-season from 2024 to 2025 as compared to 2025 to 2026,
Also, the 2025-26 period produced a bigger gap between the number of player index increases in the offseason vs. in-season, with 13 more in-season increases vs. eight during the 2024-25 period.
The median (or middle) percentage gain during the offseason was 1.31%, while the in-season median percentage gain was 7.96%, or 6.08 times higher (compared to 3.23 times higher from the 2025-26 period).
The above results indicate more player index increases during the 2025-26 period, but a more pronounced seasonality influence for 2024-25, a period during which there was less movement in the broader card market.
As further evidence of the broader card market movement this year, while the Baseball and Vintage index percentage increases during the 2024-25 offseason (0.89% and 0.77%, respectively) paled in comparison to the 2025-26 offseason percentages (12.04% and 11.72%, respectively), the in-season increase comparisons blew those away (2.63% and 0.97% in 2024-25 compared to 56.33% and 54.39% in 2025-26).
You’ll obviously want to do your own research, but it seems like seasonality does have some effect on vintage baseball card values and could thus indicate when it’s better to buy cards vs. when it’s better to sell cards.
Are you interested in further seasonality research?
