The 1899-S Morgan Silver Dollar in MS 64 is a notable coin from the iconic Morgan Dollar series, which was minted from 1878 to 1904 and then again in 1921. The S mintmark indicates that this coin was struck at the San Francisco Mint.

The 1899-S Morgan Silver Dollar features the classic design by George T. Morgan, with a portrait of Liberty on the obverse and an eagle with outstretched wings on the reverse. The 1899-S is particularly interesting for collectors because it’s part of the Morgan Dollar series that includes several key dates, and the San Francisco mintmark adds to its significance.

The MS 64 grade indicates that the coin is in excellent condition, with minimal imperfections. There may be a few light contact marks or surface abrasions visible under magnification, but overall, the coin retains much of its original luster and detail, making it a solid choice for collectors looking for a well-preserved example.

The CACG is likely a typo or misunderstanding for CAC (Certified Acceptance Corporation). If this coin has received a CAC sticker, it means that it has been reviewed by CAC and meets a higher standard of quality than other MS 64 coins. A CAC sticker typically increases the coin's value and appeal, as it assures collectors that this particular coin is a superior example of the MS 64 grade.

In summary, the 1899-S Morgan Silver Dollar MS 64 with a CAC sticker would be a highly desirable coin for collectors, offering a well-preserved example of this key date with the added assurance of the CAC certification.
