Vintage Gold-toned Metal Monogram Pin - Initials JEM with makers mark M underscore - This is an elegant classic timeless pin. In a monogram when all three letters are the same size they represent J for first name, E for middle name or maiden name, and M for last name. When the middle initial is larger then the first initial J is for you first name, the second initial E for you last name, and the third M for you middle name or maiden name. The makers mark is an M with and underscore (see photo for details). I was unable to identify the maker from this mark. This is gorgeous, large statement pin measuring approximately 2 1/2” wide and 2” tall (see photos for more details). If your initials are JEM then this is the day to get a fabulous monogrammed pin!
