π‘ Common Flaws vs. A Numismatic Masterpiece
First, let’s talk about what most people find. It’s common to find small die chips (raised blobs of metal) in the crevices of the Mount Rushmore design. These are fun, minor errors that are worth a few extra dollars to collectors.
But the $100,000 coin is not a minor flaw. It is a completely different type of coin, a special test piece that was never meant to leave the U.S. Mint.

π² The Legend of the $100,000 “High-Relief” Quarter
The six-figure valuation belongs to a coin known as the 2013 “High-Relief” Experimental Pattern.
- The Hidden Story: A Secret Test Strike The story goes that in 2012, before starting mass production, the U.S. Mint’s engraving department in Philadelphia experimented with a special “high-relief” die for the Mount Rushmore quarter. The goal was to create a coin with a stunning, sculptural 3D effect, making the presidential portraits leap off the surface. While the test was an artistic success, the high-relief design was too hard on the coining presses and was rejected for circulation. The test dies were ordered to be destroyed.
- The Mistake at the Mint: Legend says that one of these lone prototype dies was accidentally put into a production press at the Philadelphia Mint (which uses no mint mark). A very small number of these breathtaking high-relief quarters were struck and mixed in with regular coins before the mistake was discovered and the die was retired forever.
- Why It’s Worth $100,000:
- Unique Design: It features a deep, 3D, sculptural quality that is visibly different from the millions of other quarters in circulation.
- A “Pattern” Coin: It’s a test piece that escaped the mint, making it one of the rarest and most desirable types of coins a collector can own.
- Ultimate Rarity: With only a handful believed to exist, the first authenticated example to reach a major auction would cause a bidding frenzy among top collectors, easily pushing its value past $100,000.

π How to Spot a Potential High-Relief Treasure
While this is a hunt for a true “needle in a haystack,” you can train your eye to spot the difference.
- Step 1: The Visual Comparison (This is Key!) The best way to spot this error is by comparing it to another 2013 Mount Rushmore quarter.
- Lay two quarters side-by-side under a good light. Tilt them back and forth.
- Look For: Does one coin seem to have much more depth and detail than the other? On the “High-Relief” version, the shadows cast by the presidents’ noses and brows would be significantly deeper. The crevice between Washington and Jefferson (where the arrow in your image points) would look like a deep canyon compared to the gentle valley on a normal coin.
- Step 2: Look for Signs of a Special Strike A test piece might have other unique characteristics. Examine the rimβis it unusually sharp or well-formed? Is the overall strike quality exceptionally strong compared to other quarters from that year?
β What to Do If You Find an Impossible Coin
If you have a 2013 Mount Rushmore quarter that looks strikingly different and more detailed than any other, you could be holding a major discovery.
- Protect It Immediately: Handle the coin only by its edges. Place it carefully into a protective holder to prevent any scratches or damage.
- DO NOT CLEAN IT: π« Cleaning will destroy the coin’s original surface and its value. This is the cardinal rule of coin collecting.
- Authentication is Everything: π‘οΈ A discovery of this magnitude is unverified until certified by a top-tier grading service like PCGS or NGC. They are the only ones who could officially confirm it as a genuine “High-Relief” pattern.
- Contact a Major Auction House: To realize its full value, a coin like this must be sold by a world-class auctioneer like Heritage Auctions or Stack’s Bowers, who can properly market its incredible story to the right buyers.
π The Hunt for Modern Masterpieces
A modern masterpiece like the 2013 “High-Relief” Quarter could be anywhere. After more than a decade in circulation, it could have traveled the globe, perhaps sitting in a change jar right here in Siem Reap, Cambodia, brought over by a tourist. This is a reminder to always look closely at your changeβyou never know when you might be holding a piece of history.
