Hi people i have had this could charm for years never thought much of it, just wondered if you can help. the coin says rhodesia and Nyasaland half penny 1964. It looks like it could be gold or plate or something like that, has a plastic metallic green setting.
Its hard to say from a photographi but it looks like it could be a 1/2 from Rhodesia mounted to be worn...whether it is plated is impossible for me to say but the coin itself would be copper. I have one just like it, just not mounted.
Rhodesia is modern-day Zimbabwe. It looks like your item is a coin that was turned into jewelry. It would not have any value as a coin now.
