AI Appraisal Estimate

This is a United States Sacagawea Dollar coin, typically produced starting in the year 2000. This specific image shows the reverse (tails) side of the coin. The design features a soaring bald eagle surrounded by 17 stars, representing the number of states in the Union at the time of the Lewis and Clark expedition. The text 'UNITED STATES OF AMERICA', 'E PLURIBUS UNUM', and 'ONE DOLLAR' is clearly embossed. The coin is composed of a copper core clad with a manganese brass coating, which gives it its signature golden or 'brass' appearance. Measuring 26.5mm in diameter with a plain, smooth edge, this specimen shows moderate signs of circulation and age. There is visible surface wear on the high points of the eagle's wings and some light scratching or bag marks on the field of the coin. A significant amount of tarnishing or 'toning' is present, with shifts toward darker copper and brownish hues, particularly along the bottom rim and near the eagle's tail. This patina suggests the coin has been exposed to the environment rather than being stored in a mint-state protective casing. The overall strike quality appears standard for business strikes intended for general circulation.

I have carefully examined the provided images of this Sacagawea Dollar. Based on the visual evidence, the coin is a standard business strike reverse featuring Thomas D. Rogers Sr.'s soaring eagle design. The specimen exhibits 'About Uncirculated' to 'Extremely Fine' details, but shows significant environmental toning and surface bag marks characteristic of general circulation. Authenticity appears consistent with U.S. Mint production standards for the manganese-brass composition, as evidenced by the specific wear patterns on the eagle's breast and wing tips. In the current numismatic market, high-grade specimens or rare 'Cheerio' varieties (FS-902) command significant premiums; however, this specific coin lacks the enhanced tail feather detail of that variety and displays excessive patina that diminishes its aesthetic appeal to serious collectors. Comparable coins are abundant, with hundreds of millions minted between 2000 and 2001, making this a common date issue. The market demand for circulated Sacagawea dollars is minimal, typically restricted to face value unless a major mint error is present, which is not detected here. Please note that this appraisal is limited by the digital nature of the inspection. A final determination of value would require an in-person examination to verify weight (8.1 grams), diameter (26.5mm), and a microscopic inspection of the mint mark on the obverse (not pictured) to check for doubling or repunching. Scientific testing via X-ray fluorescence (XRF) would be necessary to confirm the exact metallic composition if a planchet error were suspected.
