The 1970 S penny was struck at the San Francisco Mint. While millions were made, a small number have errors and varieties that make them incredibly valuable to collectors.
The rarest 1970 S pennies are Double Die Obverse (DDO) versions. This means the design was accidentally stamped twice, creating a noticeable doubling on the date and lettering (like “LIBERTY” and “IN GOD WE TRUST”).
Look carefully at the date and inscriptions. If you notice bold doubling without needing a microscope, you could have a fortune in your hands! Sharp, clear doubling is what serious collectors want.
Coins are graded on a 70-point scale, with Mint State (MS) grades being the most valuable. A 1970 S DDO penny graded MS-65 Red is especially prized. Redder, shinier coins without scratches sell for the highest amounts.
In 2001, a pristine 1970 S DDO penny sold for an astounding $24,150 at auction. Why? It had a nearly flawless Mint State grade and vivid red color — a combination that's super rare.
Not all 1970 S pennies are double dies. A regular 1970 S penny in circulation is usually worth 1 to 5 cents. Proof versions can fetch a few dollars if they’re in great condition, but it’s the rare DDO ones that bring life-changing money.
Check old coin jars, estate sales, and inherited collections. Use a magnifying glass to look for doubling, especially around the date and letters. You never know — your penny could be hiding in plain sight!
