Though I agree it resembles a coat hanger, the photo with a ruler next to the object shows the brass section is only 1.5-inches long. That seems much to short to serve as a coat hanger or even a hat hanger. Also, the curved end only sticks up 1/2" higher than the rest of it... not enough to "grip" a coat or even a hat. So, I think this short little hanger was intended for hanging something which had a thin wire handle, which would be retained by the crook of the object's narrow fish-hook shape. That shape makes me think it was mounted under a counter or shelf (or overhead), not wall-mounted.
Just as a sidenote, I think it's kinda cool that the knob on the end of the hook is made to look like a Garnet crystal.
