Miller is the organization’s second-ranked prospect and baseball’s 46th overall. According to Market Movers, Miller saw 51.4 percent increase in sales volume thanks to his popularity in 2024 Bowman Baseball products.

Miller’s ungraded base 2024 Bowman Chrome Prospect Autograph sells in the $90-$100 range, while his 2024 Bowman Sapphire Autograph goes for around $200. If Miller keeps up this pace, we could possibly bet watching him play at Citizens Bank Park within the next couple of years. Click here to search for Aidan Miller baseball cards on eBay.

Second on the list is Minnesota Twins infielder Royce Lewis, who has just been lighting it up since he came back from injury. In 20 games, Lewis has already cranked out 10 home runs, which explains why he’s been a hobby favorite. Lewis’ cards have seen a 16.7 percent increase the past 30 days. Lewis has often been injured over his first three seasons, but if he can stay healthy, his card prices will continue to skyrocket. Click here to search for Royce Lewis baseball cards on eBay.

Aaron Judge comes in third on the Market Movers list, as the New York Yankees slugger’s sales volume increased by 8.7 percent. It’s not surprising to see as Judge is one of the more popular players collectors seek. It also doesn’t hurt that he’s putting up historic numbers once again and he’s on pace to smack another 60 homers this season. Click here to search for Aaron Judge baseball cards on eBay.

Boston Red Sox outfielder Jarren Duran shows up fourth with a sales volume increase of 8.3 percent.

Rounding out the top five is Seattle Mariners prospect Lazaro Montes. The 19-year-old outfielder was recently promoted to High-A after crushing Single-A pitching. Montes, the Mariners’ fourth-ranked prospect and baseball’s 81st overall, signed for $2.5 million when he was only 17 years old. Montes first appeared in 2023 Bowman and, as the data shows, collectors are highly pursuing one of the best Mariners’ prospects. Click here to search for Lazaro Montes baseball cards on eBay.
