Anybody Interested In Swapping Ww Lots For Singles?

Maybe a stupid question, but hey if you do not try..

As I have quite some duplication of mostly common world material. And I would still like to retain some nice collection. Would anybody be interested in swapping stamps from any given country (mostly used) for one single nice stamp.

Now starting with us and australian stamps and would like to preserve one of each. So if someone has some nice preferably mnh stamps starting from #1 they are willing to swap..then just let me know what you would like in return/looking for. Maybe sometimes I would have to add some money with it ofcourse.

Thanks in advance.
