Brandon McCarthy [Rainbow Foil] #431 2015 Topps Baseball — Card Value

Which version do you have?

For the absolute cheapest way to own it, grab the Standard version for just $1. The premium versions like Black at $12 or Snow Camo at $7 offer slight variations in aesthetics, but the scarcity differences are minimal given the low values of the higher tiers. If you are purely collecting the card itself, stick to Standard. If you want a slightly more visually interesting piece without a huge investment, the Black version is the better small splurge.
