I would agree that in some cases you can tell the difference by texture. But there is no way of knowing whether the texture is different because the card was left in a humid cellar for 50 years, or soaked in a bottle of Poland Spring last week -- which is why I think SGC just slabs them all.
I will say, however, that the Pfeister above was in water for about 10 seconds before the paper on the back peeled right off. It was not emersed in water long enough for the texture to have any noticeable effect.
