The classification “MS64” designates a specific grade on the Sheldon coin grading scale, indicating an “About Uncirculated” coin with some minor imperfections. When applied to a Morgan silver dollar, it denotes a coin that possesses most of its original mint luster but exhibits noticeable contact marks or minor abrasions. These imperfections are typically visible without magnification and prevent the coin from achieving a higher grade, such as MS65 or above. For instance, a dollar with light scuffing in the fields or a few scattered contact marks on the cheek of Liberty would potentially receive this designation.
This grading level holds significance for collectors because it represents a balance between condition and affordability. Coins in this grade are often more accessible than those in pristine, uncirculated condition, while still retaining much of their original detail and luster. These coins provide a tangible link to the late 19th and early 20th centuries when these dollars were widely circulated as currency, reflecting a fascinating period of American history and westward expansion. The value is also influenced by factors such as mint mark, year of issue, and overall eye appeal, all contributing to its desirability in the numismatic market.
