According to the U.S. Coins Guide, there are  Georgia quarters from 1999 — part of the long-running state quarters series —that have several misprinted and “stained” spots on them, which makes the quarters a hot commodity for coin collectors.  Some could be worth as much as $10,000.  Here is what you should look for:

• It was minted in 1999
• It has a golden or greenish color, similar to Sacagawea dollars
• It appears thicker than a normal quarter
• It lacks the copper (orange-colored) stripe on the edge of the coin
• It lacks some or all of the edge reeding

Over a billion Georgia quarters have been produced, so finding one of the estimated few hundred made that are worth $10,000 will be rare.
