its a 1916 ½ mark, the scarf holder is stamped DS (or BS) 835, so silver.
has been very well made, the lock is also working great. has stones around.

it has an little acorn (also very well made) on the end of the chain.

Nice litte item.The coin in a mounted and worn condition should go for melt ( 2,5 g of pure silver ) The beezle and bracelet should at least be worth their silverweight with a smal premium for the quality of the work. All in all 20-30 euros perhaps ?
