Brewers Win the World Series While Rookie Cooper Pratt Sets a World Series Rookie Record
Pratt set a World Series rookie record with six straight hits as the Brewers won their first title, and his 2024 Bowman Chrome Refractor /499 auto in PSA 10 went from $246 in the regular season to about $375 after Game 4.
Wednesday night, the Milwaukee Brewers won the World Series in five games, becoming first-time World Series champions in their 57-year history. The Brewers held the best record in back-to-back seasons, and this year, they came out on top.
It's also Milwaukee's first World Series title since the 1957 Braves. Their Series MVP, Lew Burdette, beat the Yankees three times, and his 1957 Topps card still goes for about $4 raw.
Rookie Cooper Pratt was a big reason why the Brewers won the Fall Classic. He hit extremely well, going 8-for-19 at the plate, with two doubles, a homer in Game 4, and drove in seven runs1. From Game 4 to the World Series-clinching Game 5, Pratt broke the 1978 World Series rookie record for consecutive hits, set by the Yankees' Brian Doyle, with six straight.
If you want Doyle on cardboard, his 1981 Topps card usually sells for about $1 and last went for 30 cents on Oct. 18, which is less than a raw copy of Pratt's 2024 Bowman Chrome base card.
The Brewers knew Pratt had star potential even before his call-up, handing him an 8-year deal worth nearly $51 million before his big-league debut. The team saw potential in every area of his game, and now he is a major reason the Brewers won the World Series.
His performance will not only increase his sales volume but likely his price, too, especially when he gets his rookie cards next season, because his Bowman prospect cards are already incredibly desirable, especially the autos and numbered cards.
That's already happening at the cheap end, where his raw 2024 Bowman Chrome Prospects base card sold 23 times on eBay on Oct. 28 and the morning of Oct. 29, against 11 in the four weeks before, and it still sells for about $2.
Cooper Pratt's Refractor auto stayed pretty flat from the regular season through Game 3 of the World Series, while his base auto was already up about 16%. For reference, Pratt's 2024 Bowman Chrome Prospect Autographs base auto PSA 10 has gone for a median of $300 across 11 sales during and right after his four-hit Game 4, up from $190 before the Postseason. Pratt had a red-hot October, and with that, his other cards have increased in value too.
All 11 of those base auto sales came between midnight and 1:30 a.m. Eastern on Game 4 night, the night before the Brewers clinched.
His 2024 Bowman Chrome Prospect Autographs Refractor /499 PSA 10 is an example. The median value during the regular season (up until September 29th) was $246 across 24 sales; we tracked a marginal increase from the beginning of the Postseason through his big, 4-hit World Series Game 4 performance to $253 across 4 sales, then we saw a pretty significant jump in the card's price to about $375 across 5 sales, approximately 52% above the price during the regular season. Three of the five sales after Game 4 were on Fanatics Collect, while two were on eBay. The card isn't scarce either; PSA has given a 10 to 60% of the 150 Refractors /499 it has graded, for a total PSA 10 population of 90 as of October 29.
While 90 out of a theoretical 499 doesn't seem like a lot, it's still quite a bit, because only 60 of PSA's graded copies came back below a 10: 59 PSA 9s and one PSA 8. PSA 10s consistently command the highest prices, and the fact that most graded copies are Gem Mint 10s could mean these cards were well cared for during signing and production. There could be several dozen more PSA 10s to grade; we just don't know yet, and only when the supply of 10s is large enough will we know whether that drives the market up or down.
I expect the market for Brewers cards to rise over the next several weeks as we head into a likely lockout when the labor deal expires December 12, because of the type of baseball the Brewers play. They don't have the biggest names on their roster, yet they still emerged from the 2026 Major League Baseball season as World Series champions. Whether people buy cards of key players because they respect their game and enjoy watching them play, or it's more of a long-term play, investing in younger guys like Pratt.
The Brewers also have a very exciting farm system, including MLB's Top Prospect Jesús Made, Luis Peña, Andrew Fischer, and brothers Brady and Trey Ebel3. The Milwaukee Brewers should be an exciting team to watch for years to come, especially with Jackson Chourio, Christian Yelich, Cooper Pratt, and many more players. This team doesn't have the most exciting names like the Dodgers and Yankees, but its core of young players mixed with MLB veterans shows why it not only won the most games in baseball this year, but also came out on top.
Pratt will be an amazing player, a possible future multi-time All-Star, so I'd watch his card market carefully, whether you have his cards or not, because if the market dips and you believe he will heat up again, that might be your time to buy.
