I have an old Coldspot Chest Freezer from Sears that I would like to sell.?

I have an old Coldspot Chest Freezer from Sears. I would say it is from the 60's. It is fully operational and is in very good shape. A friend wanted it out of his house, so I loaded it up and took it home last year. I was wondering if this would be something that someone might but as an antique. If so how much should I ask for it?
