Buying Slabbed cards...security...or the contrary?

[botn]

A card having been graded is not an excuse for the buyer to not know if what they are buying is in fact graded correctly. If you are relying solely on the flip to tell you the condition of the card then you are in trouble. Just like 30 years ago if you were relying solely on the dealer telling you what the grade of the card is instead or using your own judgement then you were in trouble back then.

Holders will be compromised but as has been pointed out and what I was alluding to in my first post--altered cards managing to find their way into holders has always been far more of a threat to the hobby. I have virgin 60s commons come back as trimmed yet not a day goes by where I do not come across an obviously trimmed 4 figure star card that is obviously altered.

It is my understanding the 52 Mantle in question was an actual PSA holder. Apparently the person doing this does not need to go to the expense of fabricating holders in China as he is able to use original holders.
