Over the last 10 years, the San Francisco Mint produced Silver Eagles on a very limited basis. After the year 2000, the U.S. Mint assigned the West Point branch to Mint Silver Eagles, so the San Francisco branch could concentrate on other types of coinage. Since these coins do not have a mintmark, the only way to know that they are from San Francisco is if you send a sealed Monster Box to NGC that designates it from that U.S. Mint Branch. These facts make finding San Francisco Struck Silver Eagles quite difficult, as they are very limited. It is also very interesting to note, that San Francisco Struck Silver Eagles have a distinct look when compared to other Silver Eagles. They almost appear to have a frosted, satin-like finish that the West Point versions do not have. Each one of these coins has been certified by NGC in perfect grade MS70. This is the first deal of 2012 (S) Silver Eagles we have gotten in years, so take advantage of this deal while you can.
