Side note specifically about the "Greening" / "Hulking" on Topps Finest trading cards:

That distinct discoloration you are seeing on the players' faces, which often looks like a sickly yellow, copper, or pale puke-green, is a well-known manufacturing defect in the trading card hobby known as "greening" or "hulking." It is incredibly common on 1990s Chromium-style cards, particularly early Topps Finest and Topps Chrome sets across hockey, basketball, baseball, and football.

Here is the breakdown of why this happens:

1. The Chemical Reaction (The "Why")

When Topps first introduced its premium "Finest" line and the patented chromium printing process in the mid-1990s, the technology was still experimental. The cards were constructed by layering a metallic, reflective film onto cardboard base stock, which was then printed over with inks and sealed.

Over time, a chemical reaction occurs between the chemicals in the inks (specifically the pigments used to create skin tones and lighter highlights) and the metallic chromium coating underneath. As these elements interact and oxidize over decades, the original flesh tones break down and shift into a yellow or green tint.

2. Why It Targets the Faces

You'll notice the borders or background jerseys might look completely fine, but the players' faces and arms look like they have jaundice. This is because the chemical breakdown specifically plagues the yellow and magenta inks used to mix realistic human skin tones. The darker or purely primary-colored parts of the card use different chemical pigments that are much more stable and resistant to this specific breakdown.

3. Myths vs. Reality

• It is not necessarily sun/UV damage: While UV light can accelerate it, cards kept in pitch-black, climate-controlled storage boxes or even factory-sealed packs for 30 years have still emerged from the dark completely "hulked."

• The protective peel doesn't stop it: 1994-95 Finest cards came with a clear protective film. Leaving this peel on or taking it off has no bearing on the greening, because the reaction is happening inside the ink and metallic layers, not on the outer surface.

How It Impacts Value

Topps eventually fixed this formulation around 1998, but for sets from 1993 to 1997, it is an inescapable reality.

Because it is a widespread manufacturer defect, the hobby has mixed feelings about it. Third-party grading companies (like PSA and BGS) may dock the "Surface" grade of a card if the greening/yellowing is SEVERE. Consequently, copies of cards from this era that have miraculously managed to stay bright and retain their original skin tones command a massive premium among collectors.
