2004 Extra Leaf Wisconsin Quarter
This coin’s rarity comes from a mint error that added an extra leaf to the corn stalk on its reverse side. The error appears in two variations: the “high leaf” and “low leaf” versions. This accidental feature has captivated collectors, pushing its value to an astonishing $500,000, making it the crown jewel of the State Quarters program.
1999 Delaware Spitting Horse Quarter
The Delaware state quarter features Caesar Rodney riding a horse. A unique error caused by a raised die line appears to show the horse “spitting” from its mouth. This quirky and visually amusing flaw has boosted the coin’s value, with collectors willing to pay up to $2,000 for well-preserved specimens.
2005 Minnesota Extra Tree Quarter
Minnesota’s quarter, highlighting its natural beauty, contains a fascinating die doubling error. This flaw creates the illusion of an extra tree in the forest scene depicted on the coin. Some variants show multiple extra trees, making them even rarer and valued at around $1,500.
2000 South Carolina Mule Error Quarter
The South Carolina quarter became famous for its mule error, where mismatched dies were used to create the coin. The reverse design features South Carolina, while the obverse shows an incorrect die from another coin series. This highly unusual error is incredibly rare, with values reaching $50,000 at auctions.
2004-D Florida Die Gouge Quarter
A die gouge error on the Florida quarter has collectors intrigued. This coin features a Spanish galleon, and the error resembles an additional mast or extended rigging. This minor detail has elevated the coin’s desirability, with prices around $3,000 for well-preserved examples.
2001 Kentucky Double Die Reverse Quarter
The Kentucky quarter celebrates Federal Hill, the inspiration for the song “My Old Kentucky Home.” A double die error on the reverse results in noticeable doubling of certain design elements. This flaw makes it a prized collectible, with values up to $3,500 depending on condition.
