WWII Trench Art Knife Opener Bullets & Rare Coins

I purchased this at an auction and it was sold as WWII Trench Art. It measures 12" long and the blade of the opener is a lucite plastic with beveled edges. The handle consists of several bullets and the coins are British George VI King Emperor on one side and the back side says Annas India and they are various dates from 1939 - 1944 in various amounts. I know absolutely nothing about this, but I thought it was very interesting. Please email me with any questions. Buyer pays $4.05 shipping. Good luck and thank you for visiting my auction.
