Cuckoo Clocks
Cuckoo clocks were once quite popular to include in the home, dating back to the 1730’s in Germany. While these may be outdated now, the resale market for them is quite staggering. As of 2019, some cuckoo clocks have been priced at $2000 on eBay.
Old Stamps
Collecting stamps may sound a little funny to many of us, but the joke is on us. Many old stamp sets are quite valuable, with one set going for a whopping $90,000 on eBay in August 2019. These are quite the valuable little stickers!
