These are the most interesting and delicate spoons I have ever encountered. They are handmade. The bowl of the spoon is actually a 1/4 Rupie coin from German East Africa. They are hammered into a bowl-like shape, which would allows them to be used to stir a beverage. The coins are dated from the early 1900’s. The obverse shows Wilhelm II in his Garde du Corps helmet. The reverse has the denomination of the coin, date, and location. The shaft of the spoon is knurled and is topped by a small ball. I have four of these and each is a bit different. There is some obscuring of the coin markings where the hammering took place.
