You might have heard that investing in gold is the secret to a secure, comfortable life after retirement. Whether you invest with Americo Gold or Heartford Gold, there is certainly money to be made there. However, the secret to value might already be in your pocket. That’s right—in your change! Valuable coins are more common than you think, you just have to make sure to look before you pop them into a vending machine or parking meter. Here, we’ll identify some common, valuable coins that could be hiding in your change right now:

1. 2005-P “In God We Rust” Kansas State Quarter
An intriguing minting mishap occurred with the 2005 Philadelphia minted quarter. The standard “In God We Trust” becomes a humorous “In God We Rust,” adding an extra $100 to its value. Ensure you check for the missing ‘T’ on this 25-cent coin for a unique addition to your collection.

2. 1999 Wide AM Reverse Lincoln Cent
In 1999, the U.S. Mint issued two types of Lincoln Cents with subtle irregularities, fetching anywhere from $45 to $530 depending on condition. To assess its value, you’ll need to inspect the reverse side. The ‘AM’ in ‘America’ will either be closely touching or unusually wide apart, with the latter being the scarcer variant.

3. 1970-S Small Date Lincoln Cent With a Doubled Die Obverse
A minuscule error transformed a mere $0.01 coin into a hidden gem worth a staggering $3,500. The 1970 cent features doubled lettering in the words “Liberty” and “In God We Trust.” Moreover, there’s a variant with a small date in the numerals—if the ‘7’ in ‘1970’ aligns with the rest of the numbers, you possess the rarer small date version.

4. 2004-D Wisconsin State Quarter With an Extra Leaf
Keep a keen eye on your 2004 Wisconsin state quarters; a printing blunder could fetch you $100. The coin’s reverse side showcases a cow, a wheel of cheese, and a corn cob. The anomaly lies in the corn husk. If your coin sports an additional leaf on the left side of the bottom of the corn cob, you’ve stumbled upon a rare find.

5. 1982 No Mint Mark Roosevelt Dime
Delve into the world of coins and discover the 1982 Roosevelt dime, a piece often missing the “P” mint mark for Philadelphia. This seemingly small omission elevates its value to approximately $100 when it’s in decent condition, making it a hidden treasure among collectors.

6. 1983 Copper Penny Minted on a Zinc Planchet
Ordinary pennies might not excite you, with their seemingly miniscule value. However, a 1983 copper penny struck on a zinc planchet is a hidden treasure. These pennies were meant to be made of copper but were mistakenly struck on zinc blanks, giving them a worth of up to $15,000. To identify one, you’ll need to check its weight; a copper penny would be heavier than its zinc counterparts.
