Vintage hotel keychains
If you traveled and stayed in hotels in the 1960s or 1970s, then you will surely remember the plastic diamond-shaped hotel keychains (also called key tags) from those times. They might seem tacky today but collectors are willing to pay top dollars to get their hands of key tags from popular places such as The Dunes in Las Vegas.
Keychains from less famous destinations are not as prized but they can also sell for $5 to $15 each, on e-commerce sites such as eBay or Etsy.
Antique keys
Vintage key tags are not the only items in demand. Antique keys made of iron or brass are also sought after by designers and crafters to turn them into jewelry or wind chimes. If you have such keys, you can sell them at a yard sale for $3-$5 apiece. Online, buyers will pay $10 to $15 for a single, age-patina key.
