My grandmother gave me this sterling ingot pendant over 30yrs. ago (from Scotland). In checking the marks, I noticed peculiar discrepancies. The leopard's head has a mustache, the lion rampart is head facing forward not looking towards and the date mark is missing the slash through it which would make it early 1700's. Would these type of irregularities mean it's just a reproduction? It is definitely silver. Any opinions would be appreciated as I've never looked into marks before.
Thanks, Caroline
