Kevin SaucierRebacked cards were mentioned earlier on another thread. Here is a good example of one that is all but seamless, has the correct thickness and has no obvious signs that it has been doctored...except the few I built in that can be only seen with a loupe.
Hand cuts cards with seemingly impossible or hard to believe back/front combo's (like this one) are always suspect:

The stains and discoloration on this back are not as a result of the rebacking process. They were all part of the original card. This kills the "adhesive always soaks through" theory
. It is simply not always true.

I'll add pics and things to look for on cards done well, showing slight signs of being rebacked and the obvious later.
