Which version do you have?

To simply own Muk #56 cheaply, buy the Standard version for $1. The Reverse Holo version at $5 offers a slight premium, usually indicating a different print run or minor aesthetic variation, but in this case, the difference is minimal. If budget is the primary concern, stick to the Standard. Collectors prioritizing a slightly more desirable variant should spend the extra $4 for the Reverse Holo.

What drives the price
