Marcelo Mayer [Black Eclipse Refractor] #91 2025 Topps Cosmic Chrome Baseball — Card Value

Which version do you have?

For the absolute cheapest way to own a Marcelo Mayer #91, grab the White Hole Refractor for $35. The premium versions, like the Red Flare Refractor at $360, offer higher perceived value through exclusive aesthetics and likely lower print runs. If you prioritize collecting the rarest or most visually striking piece, pay up. If budget is the main concern, stick to the lower-tier refractors like the Blue Moon or Aqua Equinox.
