Which company's holder is the best for storage coins and protect coins?

ICG, PCGS, NGC, ANACS?

YC

Ryana

NGC holders are more resistant to environmental contaminants than PCGS holders over the long term.
ICG with Intercept Shield would be best to prevent toning/corrosion from contaminants in the air.

Of course, you can buy Intercept Shield boxes for any slab.

As far as aesthetics go, my opinion is that PCGS is the best looking holder. PCGS coins usually sell for a premium as well...
