A very expensive padlock!
This padlock had a high bid of $2,225 (Plus $10 Shipping).
Wonderful Vintage Padlock from the Panama California Exposition in 1915. This is a rare, all brass padlock. On one side it reads: "Panama California Exposition 1915 Division of Works". On the other side in an elaborate shield surrounded by scrolls and a shell there is a ship going through a lock on the Panama Canal. Various sections of the scrolls commemorate "The Completion of the Panama Canal, 1915 " and "Panama California Exposition, San Diego". I believe that this lock was made and used only at the exposition for the buildings and gates. This is a very hard to find lock and is in excellent condition with the original key. A Great Find!! Lock Size: 2 " x 3." - eBay (26 January 2010)
