Excluding the pin guard, it weighs approx 2.4 grams & is 62 mm high, faintly stamped 10k to the rear, unsure if the pin is gold or gold plated. The border is slightly out of shape.
Weighs approx 7.5 grams & is 39mms high x 32mm wide. Stamped 10k on the clasp, no makers mark. Looks to date to the early 1900s. A few surface hairlines, see 1st photo.
