1980s New York City Skyline Sterling Silver Pin Onyx Fine Jewelry

Vintage 1980's NY City Skyline sterling silver and onyx moon pin by Great Falls Metal Works. Has an art deco flair to it. I only gave this a quickie polish to bring out the detail. It measures 2 1/8" long and 1 1/4" wide. The moon is genuine onyx.

The back is marked with company logo and Sterling. Excellent shape. There is a tiny hole in the back of the onyx, which was made by the manufacturer. I have seen this pin elsewhere marked $125.00 and up.
