I originally guess it must be a token for some kind of gambling centre and I think I am right.
At the top, you have the katakana "イチロク" which means 16, and at the bottom, in kanji ”一六商事", which literally means 16th business, or company. In the middle you have the word "金" which means gold.
A quick check in google seems that this might be one of the tokens used in pachinko, or literally means, gambling pinball machines.
Hope that helps
