Hi I have a Black Watch territorial badge that I find perplexing. The detail is extremely fine and the weight correct (with other "good" badges) and is quite flat. The colour looks bronze but I have not seen one like it. I have not tried to clean it. I wondered initially if it had been dug up or exposed to the elements?

Any thoughts?
