The peace sign is marked as seen in the photo ..  The key measures 2 3/8 inches in ;length. It is marked as seen in the photo and has 925 on the back of it on the top.  On the shaft of the key there is a small flaw. Could be a factory flaw or a ding from the previous owner . It small but i want to note it on my listing.  Both pieces are in decent used  condition. 

The one chain is a serpent style chain and is 18 inches long It has Tiffany & Co on the one side of that little tag and 925 Italy on the other side. The clasp works just fine.

The other chain is a 16 inch. It has the same markings on the tag as the other but it is a finer/lighter weight chain and has a smaller clasp and is hard to open. 

Bought these at an estate sale and never wore them.
