I love this pin! Most were made in the 1940's . There must have been some interest in crustaceans or sea jewelry at that time. This was purchased at a fine estate. I am not sure how old it is but it is signed on the underneath side, "MICHELE, STERLING". Ones that I have seen similar were all from the 1940s. This was black when I purchased it , I had to lightly clean it to see that it was greatly detailed and in perfect condition. This guy measures 2.25" long and almost one inch in width. He weighs 7.8 grams. He would look great on a hat, man's shirt or ladys sweater! We will ship him to you in a gift box. Thank you for looking!
