Token - I.M.F. Boards of Governors

I am going to guess your question is, “Where is this medal listed in Numista?”  The answer is here:

N#177612

What may be the metal composition of this TOKEN (I.M.F) Board of Governors 1976 annual meeting?

Thank You…

My opinion is, that this is made of bronze. Here is a listing on EBay that also says bronze. I searched through my book Franklin Mint Issues but did not find it listed.

What's the composition material used for this Bronze?

Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc)
