Remarks

Multiple-to-multiple

Many collectors prefer trading 1 for 1 in packets of say 50 to 150, or they never thought of something different. Others like to receive also something to trade-further to other swap partners. So sometimes there's an agreement of say 30 different with 5 of a kind making up a packet of 150 stamps.

Practically speaking you scarcely have all your tradables in the same precise multiple of e.g. five. There may be some items you have hundreds of a kind, others where you only have just a few or only one or two available for trade. Coming back to the example before your trading partner would never see any stamp of which you had less than five available.

As a consequence I can suggest the following:

Transcontinental exchange

If you should live in a different geographical region than Europe we can also find an agreement on a transcontinental exchange. Means that we could trade e.g. Asia-Pacific or (Southern) Africa for Europe (smaller countries for smaller countries, more common for more common and the like), of course with certain limitations if we wish. And again 1 for 1 or multiple-to-multiple. I'm very open and interested for a transcontinental exchange.
