35. Mantel Clocks (Original Price: $10-$100* Worth Today: $50-$500*)

To identify your old vintage mantel clock, look for the maker's name or company's name. You can find it near the center face, around the edge of the dial, on the backplate of the clock movement, or on a label attached to the back.

Some clocks, like the rare antique Boston #11 clock, can fetch thousands of dollars (the Boston model sold for nearly $3,000). Mass-produced mantel clocks, on the other hand, typically range from $50 to $500 on eBay. The price depends on factors such as the brand, model, and whether the clock is in working condition.
