Ebony Butt Cap with Inlaid Mammoth Ivory and Silver Coin

Detachable fighting butt showing detail of the ebony butt cap consisting of a solid silver coin (three penny piece from Britain dated 1921) inlaid in recessed mammoth ivory.

After the photo had been taken I realized that I had put the detachable butt the wrong way around so that the coin appears upside down in the photo!

I suppose the photo could be redone, although I am certain that the general idea will be conveyed without the need for this!
