This is so sad! A clock that doesn't work has very little value, because your prospective buyer doesn't know what it will cost to fix. They say in real estate that the top three criteria regarding value are location, location, location. With antiques, it's condition, condition, condition.
I'm afraid that your lock's condition has rendered it of very low value. On the retail market, you could expect to get $50 - $100 dollars for it. Perhaps your clockmaker might offer you a few dollars more because he has the ability to increase its value.
I hope this answer has been helpful to you, Jill.
