The 2004 Wisconsin state quarter produced one of the most famous and controversial modern US coin errors — the extra leaf varieties. These coins show an additional leaf on the ear of corn on the reverse design, in either a "high leaf" or "low leaf" position. Discovered in Tucson, Arizona in late 2004, these varieties sparked intense debate about their origin and remain highly collectible.
The Wisconsin quarter reverse features a cow, a round of cheese, and an ear of corn. On the error varieties, an extra leaf appears on the corn stalk that is not part of the intended design. The "extra leaf high" variety shows the additional leaf curving upward, while the "extra leaf low" variety shows it curving downward. Both are attributed to die damage or intentional die modification, though the exact cause remains debated.
Extra leaf Wisconsin quarters typically sell for $100-300 in circulated condition and $300-600+ in uncirculated. The extra leaf high variety tends to bring slightly higher prices than the extra leaf low. Condition significantly affects value, and professionally graded examples command the strongest prices. Market values have been relatively stable due to sustained collector interest.
