Justus Sheffield [Blue] #306 2019 Topps Mini Baseball — Card Value

Which version do you have?

If you just want the card, buy the Standard version for $0. The Blue ($4) and Pink ($3) versions offer slight variations, likely in design or minor scarcity, but the difference is minimal for casual collecting. Save your money by sticking to the Standard unless you specifically want the visual difference of the Blue or Pink, in which case the Pink is the less expensive premium option.
