Antique Safes/How much are these worth?


QUESTION: Just curious to see how much do you think these cannonball safes are worth?

ANSWER: Vivian, that is kind of like asking how much are cars worth.  A rusted beat up and locked up cannonball might be had for next to nothing.  Totally restored can easily kick them over $10,000.  I think you need to be more specific, possibly with pictures.  Doug

QUESTION: Well it's in pretty good condition. It belong to an old mill factory from the late 1800s. It's lock and we don't have the code to get in. But beside that it's in pretty good condition. It's about approximately 5.5ft tall. I attached the picture below.

Yes that helps quite a bit.  I really wasn't expecting a Mosler Corliss though.  I just made a trip to Raleigh a couple weeks ago to check out one that was being sold.  If you email me at I will put you in touch with the seller.  He would have a better idea of value.  Doug

This unusual and highly innovative safe from the later 1800's is a Corliss. William, the much younger brother of George Corliss of steam engine fame, spent several years perfecting this design and it was first displayed at the 1876 Philadelphia U.S. Centennial Exhibition. I do extensive patent research helping me in the study of antique U.S. safes and safe locks. Repairs and part making for antique U.S. safes of the early to mid 1800's, both key and combination. Also the study of early round door chest designs up to and including cannonball safes of the early 1900's.
