Everyone likes to find extra money in an old pair of jeans or on the back of the couch – but many may be sitting on a small fortune.
A single coin in your wallet or loose change jar can even be worth thousands of dollars, so it’s worth digging through to see if you have a rare collectible.
The Lincoln cent coin minted in Philadelphia in 1972 is worth a whopping $3,500 because of the doubling of the words on the front.
And a 1972 half dollar minted in Denver sells for about $1,000 because it lacks the designer’s initials.
The two main factors that make a coin rare and valuable are the doubling of the letters on the face, known as the double die, and whether there are any aspects of a design missing or additional details.

Steve Feltner, team leader of numismatic education and assessment, says you should prioritize searching silver coins as they are the most valuable.
He said, “It’s better to look through silver coins — dimes, quarters, and half dollars — and you’re looking for coins minted in 1969 or earlier.
“What people often look for is variety and something outside the norm of tradition.”

1972 Kennedy Half Dollar No FG Initials – $1,000
Minted in Denver, this rare half dollar Kennedy coin is worth up to $1,000 because a small percentage of the coins produced were not printed with the designer’s initials – FG for Frank Gasparo.

For those not lucky enough to come across these rare coins in their spare change, Feltner says looking for coin rolls is a good starting point to get your hands on them.
It is the process of searching through rolls of coins, usually obtained from banks, to find rare and valuable coins.
The coin valuation expert said: ‘The coin roll hunt is a good starting point for those who want to collect rare coins.
“You don’t need a lot of investment and you can figure them out while watching TV.”
But he has insisted that all coin collectors should buy the Cherry Pickers’ Guide and use it to reference any coins they find to see if they are valuable.
He added: “Education is the most important thing. The saying goes, buy the book before the mint because by spending $40 they can save hundreds of dollars on review fees.’
It costs $23 to appraise coins up to $300 with the Professional Coin Grading Service and $40 for coins up to $2,500 and there is a two-month waiting period.
