For your consideration is this large lizard pin. Signed Mexico 925. I believe he is pre 1945 before they started using government assay marks. He is a sturdy piece at 21.9 grams. The brooch has a great patina- more front than back.
This big pin measures 3 and 3/4 inches! head to tail by 1 and 3/4 inches across the widest point - back legs.
It is in excellent fully functioning condition with no damage.
