The Top 5 Sports Cards Heating Up
5. Lucas Ramirez
Lucas Ramirez is quickly emerging as one of the most talked-about young prospects in baseball. Representing Brazil in the World Baseball Classic, Ramirez captured attention with a standout performance that included a home run against elite pitching. As the son of MLB legend Manny Ramirez, he already had intrigue, but now he’s building his own narrative.
His card market has surged dramatically:
-
2025 Bowman Chrome Prospect Auto Purple Refractor /250 (Raw): From $14 → $178
-
2025 Bowman Chrome Prospect Auto Speckle Refractor /299 (Raw): Up 948%
-
2025 Bowman Chrome Prospect Auto 1st (Raw): Up 436%, from $4.50 → $96
Overall, his cards are up nearly 49% in the last 30 days. This is a classic case of international exposure driving demand. The key moving forward will be whether Ramirez can sustain performance as the minor league season progresses.
4. Mason Miller
Dominance on the mound is translating directly into hobby momentum for Mason Miller. With a triple-digit fastball and elite strikeout ability, Miller has been nearly untouchable. At one point, he retired 50 consecutive batters, an incredible feat that has collectors paying close attention.
His recent performance, including appearances tied to the World Baseball Classic, has pushed prices higher:
-
2021 Bowman Chrome Auto Refractor /499 (Raw): Up 22%, from $86 → $105
-
2021 Bowman Chrome Auto 1st (Raw): From $46 → $75
-
2023 Topps Chrome Update Rookie Auto Refractor /499 (Raw): From $31.50 → $43
Overall, his cards are up 18.8% over the last 30 days. While relief pitchers traditionally lag behind starters in long-term value, Miller’s dominance is forcing a shift in perception, at least in the short term.
3. Kyler Murray
Few things move the market faster than a high-profile quarterback change, and Kyler Murray is benefiting from exactly that. After joining the Minnesota Vikings, Murray has re-entered the spotlight as a potential franchise leader. His dual-threat ability and fresh start have sparked renewed excitement among collectors.
Key card increases include:
-
2021 Optic Downtown SSP (PSA 10): Up 27.2%, from $400 → $510
-
2019 Select Field Level Silver (PSA 10): Up 100%, recently sold for $90
-
2019 Prizm Base (PSA 10): Up 94%, from $17.50 → $46.50
-
2019 Select Concourse Silver (PSA 10): Up 46%, from $15 → $25
Overall, his market is up 25.3% in the last 30 days. This is a textbook example of offseason speculation. If Murray performs early in the season, this momentum could continue, but historically, these spikes can be temporary.
2. Vinnie Pasquantino
The World Baseball Classic continues to leave its mark on the hobby, and Vinnie Pasquantino is one of its biggest risers. Playing for Team Italy, Pasquantino delivered key hits and clutch performances that helped shape the tournament’s outcome. His ability to produce in high-pressure moments has translated into increased collector demand.
Recent card movement includes:
-
2026 Topps Golden Mirror SSP (Raw): From $65 → $100
-
2023 Topps Chrome Rookie Auto (Raw): Up 167%, recently sold at $40
-
2023 Topps Pristine Auto (Raw): Up 100%, from $20 → $40
Collectors are buying into both his international performance and MLB upside, making him one of the most interesting bats to watch heading into the season.
1. Kon Knueppel
At number one this week, it’s Kon Knueppel and his market is reaching another level entirely.
The biggest headline? A massive $397,000 sale for his Topps Chrome Superfractor Auto. That’s the kind of sale that instantly resets expectations across the hobby.
On the court, he’s delivering:
-
Averaging 21.5 points per game
-
Shooting over 50% from the field
-
Breaking rookie three-point pace records
His broader card market is surging:
-
2025 Topps Chrome Base (PSA 10): From $350 → $570
-
2025 Topps Chrome Refractors (Raw): From $62.28 → $128
-
2025 Topps Silver Pack #TC-KK (Raw): From $12 → $39
-
2024 Bowman Chrome University Refractor 1st (Raw): From $4 → $33
Knueppel is firmly in the Rookie of the Year race, and collectors are pricing in massive long-term potential. However, it’s important to recognize that this is peak early-hype territory, where volatility is extremely high.
