Does anyone collect stamps ?

[cosmicray]

I have a box of envelopes, from payments I received via mail. These are all (I think) in the 1999-2001 time frame. They have been sitting here for a long time, and I was thinking about burning them with the leaves. If anyone wants the stamps off of them, let me know. Mostly US, but a few international. There was one I received, that I probably set aside, from some country in Europe, and the stamp actually had metal foil on it. Quite unusual.
