The Coin Museum is a nice place to go to, if you are interested in coin collection. Although I am not a coin collector, I have visited the Museum before. The coins of different shapes and materials are really fascinating.
The only drawback is the English translation of the Museum Introduction there, which was probably translated by a school student. I suggested the caretaker there to get a better translation from a professional translator. I do not know if they have replaced that version by a better one or not.
