Sean Doolittle [Blue Wave Refractor] #137 2018 Topps Chrome Baseball — Card Value

Which version do you have?

For the lowest cost, grab the Standard or Refractor for around $2. The premium versions, like the Red Refractor at $25, offer significant scarcity and desirability among serious collectors. If you are a casual owner, stick to the cheaper options. However, if you are building a high-end collection, the Red Refractor provides the most tangible value increase.
