If you’ve ever spoken with a coin collector, you know just how sought-after some rare pieces can be, whether because of their history, value, or both. However, some treasured coins could be jangling in your pocket or sitting in your piggy bank. Here are a few examples of valuable currency you might already own.

3 Rare Coins That Could Be in Your Possession

1. 1999 Wide "AM" Reverse Lincoln Cent

The reverse (tails) side of the Lincoln penny has the words “United States of America” across the top. Normally, the first two letters of “America” are incredibly close or even touching. But in some 1998, 1999, and 2000 cents, the mint accidentally used a proof die on batches of circulation coins, resulting in a spaced-out “A” and “M.” Depending on the year and color, these coins can be worth up to $600.

2. 1969-S Lincoln Cent With a Doubled Die Obverse

This rare penny features a doubled die face, which means two of the same impressions are slightly offset, like a shadow. The key to finding a true treasure is in the mint mark—if everything is doubled except this mark, your penny could be worth up to $35,000. That’s because the mint mark was added after the die error occurred. If the mint mark is doubled, it’s likely a mechanical mistake called strike doubling, which coin collectors consider less valuable.

3. Presidential Dollar Edge Lettering Errors

These dollar coins feature various presidents and were first minted in 2007. The president’s name is stamped on the edge after the coin is struck. Some of these error coins feature no lettering at all or multiples on top of one another. Depending on the president, your Presidential Dollar error coin could be worth up to $3,000.
