Can ICCS Holders Be Tampered With? Are They Secure?

Way back in the day it WAS done !
Much to the detriment of the Canadian
Coin World . Nothing further need be said
on this .

As they say, "buy the coin, not the holder".

If buying expensive high grade stuff, always get clear pictures and a reasonable return policy or see it in hand.

Old ICCS holders can be great, but remember ICCS net grades and rarely marks cleaning on their holders. I recently had several huge upgrades in old holders to new, but some downgrades as well. No grader is perfect, in the next few days I hope to post a "which would you keep" on a 1858 10 cent ICCS vs. NGC.

Fake PCGS and NGC holders exist as well, just an FYI.

Thanks for the replies. Indeed they are Canada's #1 coin grading company but unfortunately they are lacking in the holder they have been using. If they upgraded their holders they would gain so much more.

Cheers
