Stunning quote on altered cards

[G1911]

I collect the card, and not the holder (I collect low grade cards and snap the slabs 100% of the time, unless the card is remaining in my trade bait box), but I think we all have altered cards. It's hard to have a lot of cards and not end up with a significant number of altered cards, altering has been common for decades. I have many I know are trimmed, recolored etc., but I'm positive I have many more I don't realize are altered. However, I personally don't really care, and remain confident I am correctly identifying that they are original authentic cards, if not able to detect all microtrimming or other alterations (I really don't check carefully for it, because I don't care much). My cards have round corners, creases, bites, holes, missing pieces, tape stains, trimming, recoloring, probably rebuilt corners and a whole lot more. None of that ruins them for me, my card isn't mint, if some one micro-trimmed an edge, that's just another type of damage.

If/when it gets to the point where I am no longer positive I am correctly identifying an authentic card, that's where I have a problem.
