The 1879-S Morgan Silver Dollar is a classic U.S. coin minted at the San Francisco Mint, with a substantial mintage of about 9,110,000 pieces. Designed by George T. Morgan, it features Lady Liberty on the obverse with the word “LIBERTY” inscribed on a Phrygian cap, surrounded by cotton and wheat, and a bald eagle holding arrows and an olive branch on the reverse. Its composition is 90% silver and 10% copper, weighing 26.73 grams and measuring 38.1 mm in diameter.

Coins graded MS65 by NGC are considered gem uncirculated, showing only minor marks and strong eye appeal. A “MEGA REVERSE ORANGE TONER” refers to vivid, naturally occurring orange—and possibly rainbow—toning on the reverse, a highly prized feature among Morgan dollar enthusiasts for its color vibrancy and originality. “DMPL OBVERSE” means Deep Mirror Prooflike surfaces, a rare technical strike where the coin displays exceptionally reflective fields, much like proof coins. The DMPL characteristic is especially desirable, indicating strong contrast between frosted devices (Liberty’s profile, hair, and cap) and mirrored fields.

The 1879-S Morgan Dollar stands out for superior strike quality typical of San Francisco-minted Morgans. The “Reverse of 1879” die variety is common for this year and usually shows strong feather detail on the eagle. Combining amazing orange target toning on the reverse with a DMPL obverse in high grade makes this particular type exceptionally beautiful and collectible for its remarkable visual appeal and technical excellence.

In summary, the 1879-S Morgan Silver Dollar with MEGA orange reverse toning and gorgeous DMPL obverse in NGC MS65 is a premium coin. It combines vibrant eye appeal and technical brilliance, making it a prized centerpiece for advanced Morgan dollar collections.
