An Unusual WW1 Aluminium Trenchart 1918 Matchbox Cover Souvenir Abbeville. It has a 1918 dated 5 Centime piece to the centre of a brass diamond shape and the centre of the coin has a red inlay. Is this a piece made at the Abbeville Hospital by a German POW? The Coin resembles a German Cap Badge with the Red Centrepiece. I wish this thing could talk!
