Blazing Skull [Retro] #5 2019 Upper Deck 80th Anniversary Marvel — Card Value

Which version do you have?

For the cheapest way to own it, grab the Color Spike version at $1. The Retro version, also at $1, offers no significant premium in edition or scarcity based on these prices. Since both are priced equally low, the decision rests on preference. If you want the absolute minimum spend, either will suffice. If you are chasing a specific aesthetic or future perceived value, you might pay slightly more later, but currently, save your money.
