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.

I DO NOT WANT TO START ANY NEW SWAPS AT THE MOMENT!
YOU CAN STILL SEND ME A SWAP OFFER, HOWEVER, DO NOT FEEL OFFENDED IN CASE I TURN IT DOWN, PLEASE.
THANK YOU FOR YOUR UNDERSTANDING.

	Feedback about gmorg on 16-Aug-2018 Two coins were missing and several ones were in very low grades. There were also unannounced year replacements, so be more accurate next time! Despite these facts, everything was fine - swap went smoothly, communication was fast and also packaging was safe (the coins were sent in a nicely stamped envelope)... Moreover, Graham did not hesitate to send another parcel with several selected coins as a compensation for the above mentioned imperfections, which I really appreciated. He is definitely a reliable swapper. Thank you for the swap!

	Feedback about Eûrn on 22-Feb-2017 A successful swap with my Canadian friend that started during his visit in Prague, where we met in person. Even though finishing it took longer, it was worth waiting for the coins. In general, I am satisfied with the swap and I already look forward for another one. Thank you, René.
	Feedback about DimoEGYPT on 10-Jan-2017 Excellent and smooth swap - fast communication, many beautiful coins, careful and safe packaging. Swapping with Maged is a pleasure - definitely 5 stars!!! I highly recommend Maged as a reliable swap partner and already look forward to another swap with him sometime. Thank you, my friend!
	Feedback about Granits on 26-Dec-2016 The swap took place approximately two years ago and I am sorry to give a relatively low rating of only 2 stars out of 5 possible. I will try to explain why: Out of 36 originally negotiated coins, 4 of them were different types and 3 more were different years than we had agreed on. Moreover, several coins I received were in very bad conditions - I even sent 4 of the received coins back to Alexander (on my costs, of course). Alexander replied to my complaints that he has some problems in his life and that he will revert to swapping later. However, he has never come back to resolving problems from our swap so far and therefore I am forced to provide him with this low rating. I have to add that especially modern Russian coins were in nice grades and worth swapping. So in case you are interested in such coins, swaps with Alexander can be recommended.
	Feedback about manelar on 20-Nov-2016 Great live swap with Manel during my stay in Barcelona. Manel is an experienced collector and a very reliable swapper. Beautiful coins, carefully packed - definitely 5 stars! Muchas gracias, Manel.
	Feedback about drnick on 12-Dec-2015 Another swap with my friend Ivan, who is for sure a very reliable swap partner. After we realized that the parcel with coins from him got probably lost during the transport, he did not hesitate to send another parcel with all the agreed coins! Therefore he deserves not only five but even TEN STARS for this swap!!! Of course, I can recommend swapping with him to everyone. I hope we make together some other swaps in the future. Thank you very much, Ivan.
