What To Do With Boxes Of Covers Mailed To New Zealand????

I have kept all the incoming covers I have received for the past 20 or so years from all over the world... what the hell should I do with them all???

Their are hundreds of topicals on them.... lots of airmail and registered covers
I would hate the chuck them out, but they have no real interest to my collection.

Ideas or requests for some types of covers considered...
I would not give them away but they would be cheap.
I just want them in the hands of people who might appreciate some aspects of some of them.

List the countries, post some pictures and sell them on SCF

Outbound postage is going to be a big problem for you. As you may know, there's a major online stamp auction in NZ where all the bidders must be NZ residents; I can't think of its name at the moment. But offering covers 100 at a time should clear your stock in a hurry.

Or, if the covers are not particularly interesting philatelic-wise, you could convert your stock to "kiloware," and sell them here, saving about 90% on postage.
