This is a "bonus set" of 50 non-random cards. It was distributed as two gold foil packs each containing 25 cards, as part of the Spider-Man Heroes & Villains: Energy Battle Special which came out between issues nineteen and twenty of the Spider-Man Heroes & Villains Collection magazine.
These Energy Battle special cards have a copyright date of 2010 on the back, two years later than the random cards #1-275 of the 2008 Spider-Man Heroes & Villains trading card set which they immediately follow.
Strictly, these aren't "Trading Cards" since they weren't randomly distributed. But they number consecutively after the cards in the earlier trading card set, and it seemed churlish not to put them into the database along with the others.
