While most quarters in your pocket are only worth 25 cents, the 2004-D Wisconsin State Quarter contains one of the most famous and lucrative “hidden” errors in modern history. Due to a mysterious die gouge (or potential intentional tampering), some of these coins feature an extra leaf on the ear of corn that isn’t supposed to be there.
As of 2026, these coins continue to command high premiums, with top-tier specimens valued at several hundred dollars.
🚨 The 2004-D Wisconsin “Extra Leaf” Error
The error is found exclusively on quarters minted in Denver (D mint mark). There are two distinct versions of this error, both located on the reverse side to the left of the ear of corn:
1. Extra Leaf “High”
The extra leaf juts upward at a sharp angle, pointing toward the upper part of the corn stalk. This version is generally rarer and more visually striking.
-
Value (Circulated): $50 – $110.
-
Value (Uncirculated/MS67): Up to $1,200+.
2. Extra Leaf “Low”
The extra leaf curves downward, appearing to “rest” on top of the wheel of cheese. While slightly more common than the High Leaf, it is still a massive find.
-
Value (Circulated): $45 – $85.
-
Value (Uncirculated/MS67): Up to $1,200.

📸 [Call to Action]
Check the Corn! Grab your 2004 Wisconsin quarters and look at the reverse side. Use a magnifying glass or a 10x loupe to look at the base of the corn ear. If you see a distinct, raised line of metal that looks like an extra husk—either pointing up or down—you have a coin worth a significant premium over its face value.
