Which version do you have?

If your goal is simply to own Aerodactyl #142, the Green Back version at $18 is the cheapest option. The Blue Back version at $13 is the lowest entry point overall.

Buyers prioritizing the absolute lowest cost should grab the Blue Back, while those wanting the slightly more desirable Green Back should pay the small premium.
