I found an old key buried under street during construction. Says "POC" or "DOC" How do I find out where it's from?
I live in St. Paul, MN
it's an old rusty key, not too large, like the same size as an old Skeleton Key & really bulky. I found in buried under the street where some road construction is going on over in the North End of St. Paul. MN. Any info on it or where I should start looking would be greatly appreciated! I've already tried googling all the key words, looking at the Minnesota Historical Society & Department of Corrections sites with no luck! Please Help!!!
