16 Things In Your House You Can Make Extra Cash From Selling

Old coffee cups

Do you have a stash of coffee cups? Before you begin your cleaning frenzy, check their price online. Collectors are more than eager to get their hands on old cups such as the ones made by Fire-King. Pieces made of opaque white glass that feature characters from the Peanuts comic strip are a hot commodity and can be sold for hundreds of dollars on eBay and Etsy if they are in good condition.

Buyers will also pay $35 to $40 for Fire-King cups made of jadeite, an opaque green glass, so search your cupboard for any of these items.

Modern paper currency

An apparently ordinary dollar bill can sell for more than face value. Why? Because it might have a fancy serial number that’s tempting collectors to add it to their collection. Check your bills for:

• Solid serial numbers: same digits (44444444)
• Repeater serial numbers: the first half of the serial number is the same as the second half (40014001)
• Ladder serial numbers: each digit is one number higher (or lower) than the previous digit (23456789)
• Very low (00000110) or very high (99999979) serial numbers

For a 2006 one-dollar bill featuring a repeater serial number, you could get around $49 on Etsy.
