Set of 4 Antique MOP Low Profile Cufflinks (Mismatch)

This listing is for a set of 4 antique cufflinks. The pieces are mismatched (not pairs) but are very similar as far as size, materials, and appearance. Each of the pieces is made of a (darkened, distressed) gold tone metal with a white, pearlescent mother of pearl face. 1 piece has a tall rounded peg backing and is marked YORK. 1 piece has a round low profile peg backing. The remaining 2 have flat rounded backs that flatten somewhat. There is normal wear throughout all the pieces, including tone darkening in the metal and wear on/around the face. To reiterate, these pieces are all individuals and do not form matching pairs, though they could be worn as pairs. Please see the pictures to see the level of wear present. I haven't tested any of the metals and can't confirm their exact material contents. Quantity: 4 (singles) Face dimensions: 13x13mm Total weight: 5.33g (this listing is marked as "low profile" to distinguish them from another listing for 4 antique MOP cufflinks in which the pieces are taller/have a taller profile)
