I picked this key up at an estate sale. I was there to buy, and honestly did not really look at it before I bought it. I assumed it was ornamental or decorative, or perhaps some sort of clock-winding key. I obviously am not a knowledgeable key collector, thus I bring it here for identification.
I hadn’t thought much about it until I showed my stepfather that day’s finds, and he immediately said, “It’s a ‘Key to the City,’ very popular in Europe.” Knowing that the previous owner had many items from Europe, I was intrigued. We looked it over and found the markings you can see in the second picture.
At this point, I haven’t any idea what this key is, if anything. I have looked at surely thousands of pictures of keys of all types, and I have been unable to find anything that resembles it at all.
Any thoughts, please share?
If more information or photographs are needed, I will provide what I’m able to.
