Back in early 2000, General Mills ran one of the most memorable promotions in American numismatic history. They tucked a shiny new Lincoln cent into 10 million boxes of Cheerios — one per specially marked box — to celebrate the new millennium.
The penny was sealed in a plastic card with a Certificate of Authenticity from the U.S. Mint, making it feel like an official collectible from day one. Most people tossed them in a drawer and forgot about them.
Every single Cheerios penny was struck at the Philadelphia Mint, which at the time did not stamp a “P” mintmark on Lincoln cents. So your coin will show just the date “2000” with no mintmark — that’s perfectly normal.

The Full Story Behind the Promotion
The Cheerios promotion was actually a cross-marketing campaign for the brand-new Sacagawea “golden dollar.” The U.S. Mint wanted Americans excited about the new coin, and General Mills was happy to help.
The prize structure was tiered. Every marked box had a penny. Every 2,000th box also included a Sacagawea dollar coin. And every 4,400th box contained a certificate redeemable for $100 in Sacagawea dollars.
About 5,500 of the Sacagawea “Cheerios Dollars” were later discovered to have a special reverse die not used on any regular-issue dollars. Those rare coins are now worth around $3,000 each — not bad for a free cereal prize!
As for the pennies, collectors initially didn’t pay much attention. That changed when researchers discovered that a significant number of these cents were struck with a rare “Wide AM” reverse die — and suddenly everyone wanted to check their Cheerios coins.
How to Identify the Wide AM Variety
This is the big question. The difference between a common Cheerios penny and a potentially valuable one comes down to two tiny letters on the back of the coin: the “A” and “M” in “AMERICA.”
On regular 2000 Lincoln cents, those letters touch at the base — called the Close AM. On the rare variety, they have a visible gap between them — called the Wide AM. This happened because a proof reverse die was accidentally used for circulation coins.
Here’s the catch: you cannot tell from the front of the coin. The difference only shows on the reverse. If your penny is still sealed in its original Cheerios packaging, you face a tough choice — open it to check, or keep the premium packaging intact.
Close AM (Common): The bottoms of “A” and “M” nearly touch. This is the standard design seen on most 2000 pennies. Worth face value to a few cents in circulated condition.

Wide AM (Rare): A clear, visible gap separates the “A” from the “M.” This was caused by a proof die used by mistake. Roughly 10% of Cheerios pennies are this variety.
Tip: Use a magnifying glass of at least 5x magnification to examine the “AM” in AMERICA. Look at the bottom serif edges of each letter — if there is daylight between them, you may have a Wide AM!
2000 Cheerios Penny Value Guide (2026)
Here’s an honest breakdown of what these pennies are actually worth today. Keep in mind that coin values always depend on condition, packaging, and market demand.
| Type | Condition | Estimated Value |
| Standard Close AM — loose | Circulated | $0.01 |
| Standard Close AM — original sealed package | Uncirculated | $5 – $30 |
| Wide AM — loose, circulated | Circulated | ~$2 |
| Wide AM — gem uncirculated (MS65+) | Uncirculated | $40 – $100+ |
| Wide AM — auction record | Top grade | Up to $800 |
| Sacagawea Cheerios Dollar (rare variety) | Any | ~$3,000 |
The original sealed packaging adds real value. A penny in its unopened plastic Cheerios card is more desirable to collectors than a loose coin, even if the grade is similar.
What Should You Do With 2000 Cheerios Penny?
If you’ve found a 2000 Cheerios penny — sealed or loose — here are the steps most collectors recommend before doing anything else.
Step 1 — Don’t clean it, ever.
Cleaning a coin destroys its numismatic value immediately. Even if it looks dull, leave it exactly as it is. A “cleaned” coin can lose 50–90% of its value to a collector.
Step 2 — Examine the “AM” in AMERICA.
Use a magnifying glass on the reverse side. Find the word AMERICA and zoom in on the A and M. A visible gap between them is the sign you’re looking for.
Step 3 — Weigh your packaging decision carefully.
If the coin is still sealed, think twice before opening it. A sealed Cheerios card in excellent condition sells for $15–$30 on its own. Opening it for a Close AM result means losing that premium.
Step 4 — Get it graded if it’s a Wide AM.
If you confirm a Wide AM variety, consider submitting it to PCGS or NGC for professional grading. A slabbed, certified Wide AM Cheerios penny commands significantly higher prices at auction.

Step 5 — Sell through the right channel.
eBay, Heritage Auctions, and Stack’s Bowers are all good platforms. For a sealed Cheerios penny, Facebook Marketplace and Etsy also work well for reaching collectors directly.
Bottom Line
The 2000 Cheerios penny is a genuinely fascinating piece of American numismatic history. Most examples are worth $5–$30 in their original sealed package — not life-changing, but absolutely worth holding onto.
The real treasure is the Wide AM variety, found in roughly 10% of Cheerios cents. If you have one in pristine, uncirculated condition — especially still sealed — it could be worth $100 or more, and top examples have fetched $800 at auction.
Before you toss that old cereal-box coin, grab a magnifying glass. You just might be holding a rare piece of history worth more than you think.
Happy hunting — and as always, handle your coins with care!
