This is a wonderful vintage Russian egg yolk amber and 875 Silver pin which dates to the 1960s. 875 silver is a lower grade than Sterling which is 925. It is hallmarked with 875 and the Russian hallmark which is a hammer and sickle with a star which was used beginning in 1958. It has a wonderful mid century modern design.
It measures 1 3/4 inches long by 1 7/8 inches across. It is in very nice condition, however there is some chipping to the amber on the central drop where it is attached, and there is a chip on the back of one of the pieces on the pin itself. The price reflects this issue and neither chip is very apparent when it is worn.
