πͺ A Wyoming Quarter Worth $500,000?
Imagine pulling a normal-looking 2007 Wyoming State Quarter from your coin jar β and discovering itβs worth over half a million dollars.

It sounds unbelievable, but numismatic experts have confirmed that one (possibly two) Wyoming quarters were accidentally struck on a 1-ounce platinum planchet, a blank intended for platinum bullion coins. If another example surfaces, it could instantly become one of the most valuable modern U.S. coins ever found. ππ°
Before you spend your change, hereβs exactly how to check.

π Step-by-Step: How to Identify the Platinum Quarter
1οΈβ£ Weigh the Coin (Most Important Step)
- Use a digital jewelry scale

2οΈβ£ Examine the Color and Luster
- Platinum has a bright, mirror-like finish
- It looks different from silver or nickel
- The surface appears denser and richer
π‘ Place it next to a normal quarter β the difference is instant.
3οΈβ£ Inspect the Edge
- A real platinum coin has a solid, uniform edge
- No copper βsandwichβ layers should be visible
- The edge should appear smooth and consistent

β οΈ Beware of Fakes and Misidentifications
As excitement grows, so do scams. Watch out for:
- π« Online listings that sound too good to be true
- π« Coins weighing ~6.25 g (silver planchets worth $50β$100, not platinum)
- π« Claims that βmany existβ β this is false
β Always verify through:
- PCGS (Professional Coin Grading Service)
- NGC (Numismatic Guaranty Company)
π¬ Request an XRF metal analysis to confirm platinum purity.
π§€ What to Do If You Think You Found One
Follow these steps exactly:
β DO:
- π§€ Handle only by the edges (cotton gloves recommended)
- πΈ Take clear photos from multiple angles
- βοΈ Photograph the coin on a scale showing the weight
- π Submit to PCGS or NGC immediately
- πΌ Sell only through elite auction houses:
- Heritage Auctions
- Stackβs Bowers Galleries
β DONβT:
- π« Never clean or polish the coin
- π« Avoid private, unverified buyers
- π« Do not ship uninsured
β οΈ Even one wipe could destroy six figures in value.
π Where Could a Platinum Quarter Be Hiding?
Collectors believe possible locations include:
- πΉ 2007β2008 bank coin rolls
- πΉ Old tip jars and cash registers
- πΉ Change from international travel
π¬ Collector Fact: A six-figure 1943 copper penny was once discovered in a laundromat. History shows miracles happen.
