The Mystery Behind the 1970-S Proof Washington Quarter
The 1970-S Proof Washington Quarter may look like any other quarter at first glance, but it’s far from ordinary. It was minted in San Francisco as part of a collector’s proof set. However, an unusual error occurred during production. A few of these quarters were mistakenly struck on planchets intended for foreign coins—creating an entirely different category of rarity.
The foreign planchet makes these coins lighter and thinner than standard quarters. This unique error adds an incredible backstory to the 1970-S Proof Quarter, making it a coveted treasure in the numismatic world. For coin collectors, these unexpected mistakes are what dreams are made of.
What Makes This Rare Quarter So Valuable?
The 1970-S Proof Quarter is a rare gem because it embodies two key factors: rarity and a fascinating minting error. Unlike regular coins, proof coins are struck with special dies, giving them a sharper, mirror-like finish that enhances their details.
Adding to its allure is the fact that minting errors are not supposed to exist. Coins like this are the result of an unusual mishap that somehow evaded the rigorous quality control processes at the mint. The rarity and intriguing story of this coin make it a “must-have” for serious collectors.
In 2016, one of these quarters was auctioned for a staggering $35,000, proving that a little mistake can turn a simple coin into a fortune.
How to Identify the Rare 1970-S Proof Washington Quarter
Finding a rare quarter like this one requires a trained eye and some patience. Here are the key identifiers to look for:
- “S” Mintmark: Look for the “S” mintmark on the coin’s obverse (front), indicating it was minted in San Francisco.
- Weight and Thickness: The rare version is noticeably lighter and thinner than a standard quarter.
- Proof Quality: The coin should have a shiny, mirror-like finish typical of proof coins.
If you believe you’ve found one, it’s essential to have the coin authenticated and graded by a professional coin grading service like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Corporation).
Other Rare Quarters That Could Be Hiding in Your Change
While the 1970-S Proof Washington Quarter is one of the most intriguing examples, other rare quarters are also worth your attention:

Tips for Coin Collectors: What to Do If You Find a Rare Quarter
If you suspect you’ve found a rare quarter, follow these steps to maximize its value:

Why Minting Errors Are Collectors’ Favorites
The appeal of minting errors like the 1970-S Proof Quarter lies in their uniqueness. Coin collectors value these mistakes because they defy the standard expectations of uniformity in coin production. Each error coin tells a story—of human oversight, mechanical glitches, or historical events—that adds to its mystique.
For collectors, these coins are more than just money; they’re tangible pieces of history, blending artistry, craftsmanship, and serendipity.
