1999 Delaware Spitting Horse Quarter: A Quirky Error
The Delaware quarter features Caesar Rodney riding a horse, but an unusual error made the horse appear to be “spitting” due to a raised die line. This quirky feature has made the coin highly sought after, with collectors paying up to $2,000 for well-preserved examples.
2005 Minnesota Extra Tree Quarter: A Surprising Error
The 2005 Minnesota quarter showcases the state’s natural beauty, but a die doubling error caused the appearance of an extra tree in the forest scene.

2000 South Carolina Mule Error Quarter: A Rare Mismatch

2004-D Florida Die Gouge Quarter: A Minor Yet Desirable Error
On the 2004-D Florida quarter, a die gouge error creates the illusion of an extra mast or extended rigging on the Spanish galleon depicted on the reverse. This subtle error has increased the coin’s value, with well-maintained specimens fetching prices around $3,000.
