Mr. Weber thought that the glass that he got from his grandfather when he was a young boy was a copper cup and seemed to have left it as it was in the storage area, but thinking that if he is arranging his / her luggage for moving, it might be gold As a result of requesting experts to analyze, I found out that it was a golden cup made in the era of the Achaemenian dynasty Empire.

Pretty detailed parts are built in.
