The way I see it is that it is like any other collectible. When you get a repro label it is like restoring it it is not worth as much as original but it still looks good. Think about it would you rather buy a 1970 Challenger in original condition if the paint was all chipped, scratched, and rusted or a restored one?

This is why I tend not to have a problem with putting a new label on a very damaged game. Eventually all collectible items get to the point where they need a little restoration. BUT, and this is a big but, it should always be mentioned when reselling that the label is a reproduction.
