Very unusual hand-made antique coin stick pin. The date and construction suggest it is a WW1 trench art piece, with a sweetheart's initials engraved. Coin is Belgian from 1910. The back has been smoothed off and engraved with initials. It has been hand constructed with an old Victorian style brooch pin, and the coin can flip up and down. Unsure of denomination, I believe it is 5 Centimes. 

Will be supplied with a modern end-cap for safety.

Approx length 4 cm / 1.5 in
Small item. See photos with hand and ruler for sizing.

CONDITION:
