Please help identify this "token"?

I have no clue what this is. The only thing I know is that is Masonic.
Outside reads:
Kilwinning Chapter No. 50 R-A-M
Any help is truly appreciated or info towards researching it.

Here's one very similar to yours. Also, if chapter and lodge are the same thing, then lodge No. 50 was formed in Trenton, NJ in 1858 and is still in existence.

KILWINNING CHAPTER NO 50 R.A.M / (Masonic keystone) (TC-434008)
