Tracking the 1,000 cards with the most quantity

I’ve been monitoring the 1,000 cards with the most quantity on comc.com. The baseball card with the highest quantity is Bo Jackson’s 1987 Topps rookie card. #1 by far. 1,657 of these cards are available on comc.com.

The four baseball cards with the most quantities on comc

Card	Player	Count
1987 Topps – [Base] #170	Bo Jackson	1,607
2013 Bowman Draft Picks & Prospects – [Base] #1	Yasiel Puig	1,101
1987 Topps – [Base] #320	Barry Bonds	1,076
2017 Bowman – [Base] #25	Yoan Moncada	1,016

The players with the most cards in the top 1,000

Player name	Number of cards in top 1,000
Nolan Ryan	35
Mike Trout	18
Cal Ripken	17
Gavin Lux	16
Mark McGwire	13
Ken Griffey Jr.	13
Luis Robert	12
Cal Ripken Jr.	12
Eloy Jimenez	11
Barry Bonds	11
Kyle Lewis	10
Juan Soto	10

Curious that even though Bo Jackson’s 1987 Topps has the most quantity. Bo Jackson doesn’t have THAT many other cards in the top 1000. His name doesn’t appear in the top 12 player list.

Change over time

Since I record the quantities daily, I can also see which cards have been added the most in the past seven days. So far it’s been fun seeing which cards are getting the most added.

Cards with most supply (and least demand)

Cards with the highest increase in the past seven days:

39 more cards added:
• 2018 Bowman Draft – [Base] #BD-38 – Nick Madrigal
• 2018 Bowman Draft – [Base] #BD-188 – Luis Robert
• 2018 Bowman Draft – [Base] #BD-165 – Nico Hoerner
(I’m assuming someone just dumped a bunch of 2018 Bowman Draft cards into the system.)

36 more cards:
• 2022 Bowman – Chrome Prospects #BCP-82 – Aeverson Arteaga

34 more cards:
• 1987 Topps – [Base] #620 – Jose Canseco

32 more cards:
• 1987 Topps – [Base] #393 – Pete Rose
• 1987 Topps – [Base] #200 – Pete Rose

Oh, I should note that these aren’t just cards being added. I’m looking at the total quantity of the cards available every day. So when a particular card goes up, that’s just people adding the card to the site. But also mixed into that number are people buying the card. 45 Gavin Lux cards were added in the past seven days. But three Gavin Lux cards could have been bought, so it’s 48 Lux cards added.

I don’t have access to the number of cards sold.

What my numbers do show is supply and demand. Is more supply being added than there is demand? There is a lot of supply for Gavin Lux. But not much demand.

Players who have increasing quantity in the top 100

Cards with most demand (and least supply)

Cards with most decrease in quantity:
45 less cards
2020 Topps – [Base] #292.1 – Base – Gavin Lux (Batting)

(I’m guessing someone just went on a shopping spree and bought 45 Gavin Lux cards for some odd reason)

18 less
1990 Score – [Base] #560 – Ken Griffey Jr.

17 less
2022 Topps Update Series – [Base] #US97 – Rookie Debut – Julio Rodriguez
2022 Topps Update Series – [Base] #US20.1 – Spencer Torkelson (Vertical)

Thus, lately, these cards have more demand than supply.

Players with the most cards whose quantity is decreasing (aka being bought)

Player name	Number of cards with decreasing quantity
Ken Griffey Jr.	4
Gleyber Torres	4
Spencer Torkelson	3
Bo Bichette	3
Tony Gwynn	3

It’s only been one week, so the sample size is small. We’ll see how this develops over the following months.
