5. Cuckoo Clocks
If you find any cuckoo clock from a yard sale, grab it and ask questions later. Even the quirky small brands can sell for $100 for more. There are some clock fanatics out there who literally have an entire wall or room of their house dedicated to clocks. If you can find a clock that has some other special value to it, that’s worth buying as well. For example, I bought a Disney Snow White clock at a yard sale for $1. It was signed by Adriana Caselloti, the actress who played the voice of Snow White. After having her signature authenticated by a Disney expert, I was able to sell it for $150.
The most expensive cuckoo clocks you can find are the German Black Forest Cuckoo Clocks, which go for thousands of dollars. I found a German Black Forest cuckoo clock at a yardsale, and paid just $5 for it. The clock wasn’t in working condition, and missing parts. I was still able to sell it on eBay practically overnight for $350. The person who bought it probably fixed it up and resold it for over $1,000. There is a Swiss Black Forest cuckoo clock from the year 1900 currently listed on 1stDibs for $30,000.
