Ex estate from which the owner collected small & interesting curios & collectables, no other history is known about the item and I have no way of verifying it’s authenticity. Apparently the club only operated for a very short period of time 1848 - 1851 making it quite scarce. A closer examination failed to find any hallmarks. Neatly engraved interwoven lettering MSC. 28mm in diameter & would weigh approx 7 grams.
