T206CollectorThe argument that trimming a card is the functional equivalent of corner wear is absurd and really does not deserve much attention. One is the intentional destruction of the original composition of the card, the other is the normal wear and tear inherent in things old. It's the difference between amputation and a skinned elbow.
The statement that "with re-backing again the composition of the card is the same" is just false. This comment also deserves little attention. I don't think you seriously believe what you wrote and so I will not entertain your hypothetical.
Trimming and rebacking are detectable alterations. I therefore have an issue with them. If trimming and rebacking were undetectable alterations then we would have a very different hobby indeed.
Your best effort at equating trimming with soaking was when you said you'd hire some paper conservators and see what they had to say. What has happened with that effort?
