What Is the 1918-S Wheat Penny?
The 1918-S Wheat Penny is a Lincoln cent struck at the San Francisco Mint in 1918. The small “S” mintmark appears just below the date on the obverse (front) of the coin. That little letter makes a big difference in value. San Francisco produced around 34.6 million of these cents that year, which is a decent mintage — but far fewer than Philadelphia’s output. Over a century of circulation has made high-grade examples genuinely hard to find, which is great news if you happen to have one in good shape.
These coins were designed by sculptor Victor D. Brenner and feature the portrait of Abraham Lincoln on the front, with two wheat stalks framing “ONE CENT” on the reverse. That classic design is why collectors still love them today. The CoinKnow app is a fantastic tool for identifying which mint your Wheat Penny came from and instantly comparing it to current market values.

How Much Is the 1918-S Wheat Penny Worth by Grade?
Condition is everything in coin collecting. A coin that spent decades in a pocket is worth far less than one that was tucked away in an old collection. Here’s a breakdown of typical 1918-S Wheat Penny values across different grades:
| Grade | Description | Estimated Value |
|---|---|---|
| Good (G-4) | Heavy wear, design visible but flat | $0.50 – $1.00 |
| Very Good (VG-8) | Moderate wear, some details remain | $1.50 – $3.00 |
| Fine (F-12) | Even wear, lettering clear | $4.00 – $7.00 |
| Very Fine (VF-20) | Light wear on high points | $8.00 – $15.00 |
| Extremely Fine (EF-40) | Slight wear, sharp details | $20.00 – $35.00 |
| About Uncirculated (AU-50) | Trace wear only, mostly lustrous | $40.00 – $65.00 |
| Mint State (MS-63+) | No wear, original luster | $80.00 – $150.00+ |
For a deeper look at 1918-S Wheat Penny prices in mint state red grades, auction records show that top-condition examples can sell for significantly more when they carry full original red color.

What Makes the 1918-S Wheat Penny More Valuable?
Not all 1918-S Wheat Pennies are equal. Several factors can push your coin’s value well above the averages listed above.
Color designation plays a huge role in mint state coins. Grading services like PCGS and NGC assign color grades — Red (RD), Red-Brown (RB), or Brown (BN) — to uncirculated cents. A red example with original copper luster is worth two to three times more than a brown example in the same numeric grade. Strike quality also matters. Some 1918-S cents came out of the mint with weak strikes, especially on Lincoln’s cheek and the wheat details. A sharply struck coin stands out and commands a premium.
Error coins are another reason to look closely. Doubled dies, off-center strikes, and repunched mintmarks are all documented on Wheat Pennies from this era. If something looks “off” about your coin’s lettering or mintmark, it might actually be worth examining more carefully — sometimes that oddity is money in your pocket.

– Coin shows and local coin dealers — A knowledgeable dealer can give you a quick in-person assessment at no cost.
– Online marketplaces — eBay sold listings are a great way to see what real buyers have recently paid for similar coins.
– Professional grading services — PCGS and NGC offer coin authentication and grading. For coins potentially worth $50 or more, third-party grading adds credibility and often increases resale value.

Tips for Storing Your 1918-S Wheat Penny
If you’ve decided to hold onto your coin, proper storage matters. Never clean a coin — even light polishing destroys the surface and can drop a coin’s value by 50% or more. Store it in an acid-free coin flip, a hard plastic holder, or a certified PCGS/NGC slab if it’s already been graded. Keep it away from humidity, direct sunlight, and PVC plastic (common in cheap coin albums), which can cause green corrosion called “PVC damage.”
The CoinKnow app also offers storage tracking features, so you can log your collection digitally and monitor value changes over time — a smart move for anyone building a Wheat Penny set.

FAQ
Q: How do I know if my penny is the 1918-S and not the 1918 Philadelphia issue?
A: Look just below the date on the front of the coin. If you see a small “S,” it was made in San Francisco. No mintmark means Philadelphia. A “D” means Denver.
Q: Is a cleaned 1918-S Wheat Penny still worth anything?
A: Yes, but significantly less. Cleaned coins typically sell for 50–80% below their uncleaned equivalents in the same grade. Professional graders will note “cleaned” or “altered surfaces” on the holder, which reduces collector interest.
Q: Are any 1918-S Wheat Pennies considered rare?
A: The coin itself isn’t considered rare in worn grades, but finding a fully red, sharply struck mint state example is genuinely difficult. MS-65 Red examples can sell for $300 to $500 or more at auction, making high-grade survival the real rarity here.
