3 Rare State Quarters Worth Almost $200 Million, Most Valuable State Quarter Errors

The State Quarter Program, which ran from 1999 to 2008, not only offered a fresh look at the rich tapestry of U.S. history and geography through its designs but also introduced some of the most interesting and collectible modern U.S. coins. While most state quarters hold a nominal face value of 25 cents, certain rare minting errors have catapulted these ordinary coins into the realm of treasures worth millions, making them some of the most valuable modern coins in U.S. numismatic history.

.1. The Delaware “Spitting Horse” Error: A Mistake Worth Millions.
.An Error Leading to a Historical Windfall.
The 1999 Delaware State Quarter was the first to be released in the State Quarter Program and quickly became one of the most sought-after due to a distinctive minting error known as the “Spitting Horse.” This error features a die flaw that causes a line to extend from the mouth of Caesar Rodney’s horse, giving the illusion that the horse is spitting. This quirky mistake has turned the Delaware quarter into a collector’s gem, with pristine-condition specimens valued at up to $150 million.

.2. The Wisconsin “Extra Leaf” Quarter: A Rarity in Agriculture.
.A Tiny Leaf’s Big Impact on Value.
In 2004, the Wisconsin State Quarter, which prominently features a cow, a cheese wheel, and a corn stalk, was subject to a fascinating minting error. This error produced quarters with an “Extra Leaf” on the corn stalk, in two distinct variations: “High Extra Leaf” and “Low Extra Leaf.” These variations have become a highlight of numismatic collections, with each variant drawing significant attention from collectors willing to pay large sums for well-preserved pieces.
