A single 1999 Lincoln Cent with a rare reverse design error just shocked the coin world by selling for $138,000! 
Known as the “Wide AM” penny, this transitional rarity hides in plain sight — and yes, it could be sitting in your change jar right now.
What Is the 1999 “Wide AM” Error?
In 1999, a small batch of pennies were struck using the wrong proof dies, creating a unique reverse design variety.
Here’s what to look for:
“AM” in “AMERICA” → Wide gap between letters (normal cents have them nearly touching)
“FG” initials → Serif font (regular strikes use sans-serif)
No Mint Mark → Only struck at the Philadelphia Mint
