Which version do you have?

If you simply want Magikarp #129, the Blue Back at $36 is the cheapest option. The Green Back at $32 is the lower-priced alternative, but neither version offers significant premium value in terms of special edition status or scarcity based on these prices. Therefore, if budget is the primary concern, buy the Green Back. If you are willing to spend slightly more for a different aesthetic, the Blue Back is available.
