"This mint quality piece is a Roman bronze key that dates circa 1st-2nd century A.D.  This piece is approximately 2 inches long, by .75 inches in diameter for the ring seen at the terminal end.  This piece has a beautiful light blue to green patina with some spotty red highlights.  This piece is in better condition than most examples, and is a mint quality piece with well defined groves seen at the end.  This piece may have fit a personal strong box, or possibly a small door.  This type of key is also published in \"Handwerk und Berfude in der Romischen Stadt', by Rieche &amp; Schalles, Cologne, 1994, pp. 46-47.  This piece is a nice example of a Roman bronze that was individually owned by a Roman with some means.  This piece also hangs from a custom stand, and can easily be worn today in a necklace.  Ex: Private New York collection.  I certify that this piece is authentic as to date, culture, and condition:   "^^<http://www.w3.org/2001/XMLSchema#string>
