๐ช A Wyoming Quarter Worth $500,000?
Imagine pulling a normal-looking 2007 Wyoming State Quarter from your coin jar โ and discovering itโs 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. ๐๐ฐ
Before you spend your change, hereโs exactly how to check.

๐ Step-by-Step: How to Identify the Platinum Quarter
1๏ธโฃ Weigh the Coin (Most Important Step)
- Use a digital jewelry scale
- A genuine platinum error will weigh 31.1 grams
- Anything near 5โ6 grams is a normal quarter
โ ๏ธ If it weighs 31 grams โ stop immediately and protect the coin.
2๏ธโฃ 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
๐ก Place it next to a normal quarter โ the difference is instant.
3๏ธโฃ Inspect the Edge
- A real platinum coin has a solid, uniform edge
- No copper โsandwichโ layers should be visible
- The edge should appear smooth and consistent

โ ๏ธ Beware of Fakes and Misidentifications
As excitement grows, so do scams. Watch out for:
- ๐ซ Online listings that sound too good to be true
- ๐ซ Coins weighing ~6.25 g (silver planchets worth $50โ$100, not platinum)
- ๐ซ Claims that โmany existโ โ this is false
โ Always verify through:
- PCGS (Professional Coin Grading Service)
- NGC (Numismatic Guaranty Company)
๐ฌ Request an XRF metal analysis to confirm platinum purity.
๐งค What to Do If You Think You Found One
Follow these steps exactly:
โ DO:
- ๐งค Handle only by the edges (cotton gloves recommended)
- ๐ธ Take clear photos from multiple angles
- โ๏ธ Photograph the coin on a scale showing the weight
- ๐ Submit to PCGS or NGC immediately
- ๐ผ Sell only through elite auction houses:
- Heritage Auctions
- Stackโs Bowers Galleries
โ DONโT:
- ๐ซ Never clean or polish the coin
- ๐ซ Avoid private, unverified buyers
- ๐ซ Do not ship uninsured
โ ๏ธ Even one wipe could destroy six figures in value.
