Most of us have a jar of pennies somewhere — a kitchen drawer, an old coffee can, the bottom of a car cup holder. We barely give them a second look.

However, one particular penny hiding in spare change across the country could be worth as much as a car, and there's a legit chance one of them is sitting in a Minnesota change jar right now.

It's called the 1982-D Small Date copper penny, and it's one of the most sought-after modern coins in America. Here's the kicker for people in the Land of 10,000 Lakes: the very first one ever confirmed was discovered by a Minnesota collector.

So, this isn't just a fun "what if"; a penny worth thousands has already turned up in our state once.

Before you go dumping out the piggy bank, here's what you need to know about this little copper treasure, including the four things that separate a $15,000 penny from a regular one-cent piece.

Minnesota's Important Connection To The Treasure Penny

The first 1982-D Small Date copper penny ever confirmed was reportedly discovered by Paul Malone, a collector from Minnesota, and it sold for a stunning $18,800 at a Stack's Bowers auction back in August 2017.

For years, coin experts had only theorized that such a penny existed. Malone's find proved them right.

Then, a second coin surfaced a couple of years later and, according to a profile of the coin, sold for $10,800. To this day, those are the only two ever confirmed — which means there could be more out there somewhere, waiting to be found.

So what would one be worth today? Estimates vary, but appraisers at American Rarities suggest even a circulated example could fetch upwards of $15,000, with a high-grade specimen likely commanding a mid-five-figure price at auction, like the original $18,800 sale.

In other words, if you found one, you'd be holding one of the most valuable pennies in the country.

Why This Penny Is Worth So Much

The value comes down to a happy accident at the U.S. Mint. In 1982, the rising cost of copper pushed the Mint to switch the penny from its traditional copper composition to the cheaper copper-coated zinc we still use today.

During that changeover, a few leftover copper blanks accidentally got struck with the new dies, the same kind of fluke that created the legendary 1943 copper penny.

The result is a coin that, frankly, shouldn't exist, and because only a tiny number slipped through, finding one is like spotting a needle in a haystack of nearly 17 billion pennies minted that year.

The good news? It looks just like an ordinary penny, so it could easily be passed over in everyday change, and you could be the one to notice it.

The 4 Things To Look For

Authenticating one of these requires hitting all four marks. Miss even one, and it's just a regular penny. Here's the checklist, according to numismatic experts:

1. The Date. It has to read 1982. No exceptions. This was the only year the Mint made the switch, so the date is your starting point.

2. The "D" Mint Mark. Look just below the date for a small letter "D," which means the coin was minted in Denver. The valuable transitional error only exists with the Denver mint mark — a plain 1982 or one with no mint mark won't cut it.

3. The Weight. This is the big one. A genuine copper penny weighs about 3.1 grams, while the common zinc version weighs roughly 2.5 grams. That difference is tiny, so you'll need a sensitive digital scale — the kind jewelers use. These have gotten cheap, often running around $15 online.

4. The Small Date. This is the trickiest part, so grab a magnifying glass or zoom in with your phone camera. On the Small Date version, the numbers in the 1982 line up evenly across the top and bottom, and the "2" has a little serif with a curved base. On the more common Large Date, the "8" sits noticeably higher than the other numerals.

So, Should You Start Checking?

Here's the honest truth: the odds are long. Only two of these have ever been confirmed in more than 40 years, so nobody should expect to retire off their change jar.

But that's also what makes it fun. The coin could be anywhere: a register till in Duluth, a coin roll from a Twin Cities bank, or a forgotten jar in a Minnesota basement. It can't hurt to take a second look at your pennies.

If you do find a 1982 penny that hits all four marks, don't sell it at the first offer. The smart move, according to numismatic experts, is to have it authenticated by a professional grading service like PCGS or NGC before anything else.

Then again, even if your pennies all come up ordinary, you'll never look at your spare change quite the same way. Happy hunting.
