What he/she collects

I collect world coins by type, typically those made from non-precious metals since the end of World War II.

What he/she wants

I am interested in almost any coin type that I do not have in my collection yet.

I would like to swap my duplicates for coin types I do not have.

Due to postage fees I prefer swapping more coins at once, preferably at least 15.

5/55/55/55/55/5 mIklun314's feedback on 1-May-2017
``Live Swap``Probably the best way to swap. Martin visited me in Stockholm and we performed a live swap. Great coins and really fun to meet a coin-collector from a foreign country. It was easy to agree and swap when you have all the coins on the table. Hope to see and swap with you again. 5 stars from me , no doubt about that.
Thanks Martin.
