Estimated Value– That is a tough one to answer. Do you want a value for insurance purposes (as part of a collection)? Are you trying to buy this off of someone (for your collection or so you can resell it for a profit)? Are you trying to sell this and you really have no idea of it’s worth? You had to have paid something for this or it was given to you, so you have some base line.That all being said, I’ve seen these old hand operated units sell anywhere from $5 up to $250.To a collector of Yale products this might be worth the upper end,but that depends alot on it’s overall condition.To someone into locksmithing on the hobby side it would be more towards the lower end of the price. You see electric and hand operated key machines on Ebay all the time and the prices really vary. Mark
