For myself, when something has absolutely, positively been confirmed as a forgery, I'm all for indelibly marking it as such.

That`s a really good advice... (my father did the same with some stamps he was able to identify)... so I`m a heir, that not just won`t be recirculating bad material as good, but in case of some issues can observe the differences easier.
