Gold cards getting spots? What collectors see, and how to protect yours
Collectors are posting photos of the new gold Mega cards with dull spots spreading over the gold surface. Here is what they report, what might cause it, and what you can do today.
Which cards are we talking about? The gold cards from the Mega Evolution sets. The original name is MUR (Mega Ultra Rare), which is what the Japanese cards say. In English they are called Mega Hyper Rare (MHR).
What collectors are reporting
On Reddit, the topic keeps coming back in r/PokemonTCG:
- “The Mega Hyper Rare gold card degradation is real”
About a month ago · 570+ upvotes · 180+ comments
A collector shows small spots spreading over the smooth gold areas of a card they took good care of. Others reply with the same thing on gold Charizard, Zygarde and Dragonite cards. One collector says their card came out of the pack with dots already.

A graded Mega Dragonite ex (PSA 6) with a gold surface that looks like something is growing on it. Several people say they have seen the same on other new gold cards. One collector says their card looked perfect when they sent it in for grading, but had tarnish when it came back. Another says their PSA 10 Lucario has become mottled since.

Not everyone has it. Several collectors say their gold cards still look like the day they pulled them. They keep them in a sleeve and toploader, in a binder or box, often with silica gel. Some think a few of the damaged cards were already damaged before grading.
Good to know: the small shiny dots in the gold pattern are normal. They are part of the design. The problem is dull, light-colored spots that grow over the smooth gold areas.
It is also not completely new. In 2017, collectors on Elite Fourum already noticed speckling on gold Hyper Rares from Sun & Moon (the older gold cards, before MUR and MHR).
What could cause it
Nobody knows for sure yet, and we have not seen an official statement from The Pokémon Company. These are the possible causes collectors mention:
- 1Production. Many collectors think the gold layer itself is the problem. One theory: the ink and the gold foil do not bond well, so the smooth areas slowly lift.
- 2Humidity. The cause mentioned most. Collectors who live in a dry place report fewer problems. And a slab is not moisture-proof.
- 3Grading and slabs. Some cards changed while they were at the grader or inside the slab. The pressure when the slab is sealed might also play a part.
- 4Cleaning products. One collector saw more damage on cards they had treated with card spray or polish.
- 5Oil from your fingers. Skin oil sticks to the card surface and shows up as marks. It might play a part too. That is not proven.
What about Japanese MUR cards?
Collectors are asking, but so far we have not seen reports about Japanese MUR cards. We would still be careful with those too.

How to protect your gold cards
- Put them in a sleeve and a toploader right after opening.
- Hold them by the edges. Don't touch the gold surface.
- Keep them dry: a closed box with a few silica gel packs. A cheap hygrometer tells you how humid your storage spot is.
- Don't use cleaning sprays or polish on gold cards.
- Keep them out of the sun and away from heat.
Wait with grading
- Wait a few months and check if your card stays clean.
- Several collectors advise not to grade these cards at the moment.
- Want to grade one anyway? Some collectors choose Beckett, because they put the card in a sleeve inside the slab. But there are also reports of gold cards that got damaged when Beckett sealed the slab. No grading company is proven safe for these cards yet.
Buying a gold card?
- Zoom in on the photos of the gold surface first. That is where the spots show.
- Ask the seller for an extra photo at an angle, in good light.
- On GoSwapCards every listing has photos, so you can check the card before you buy.
