I have two beautiful Polish silver proof coins for swap:
1. 10 zlotych 100 years of Warsaw University of Technology (mintage up to 30,000 pieces) 2015
2. 10 zlotych 200 years of University of Warsaw (mintage up to 20,000 pieces) 2016
Both coins are in original boxes with corresponding certificates.
I would gladly swap these coins.
Feel free to PM me.Regards,
