Sac

Sacagawea Dollar

Sacagawea Dollar

 

The Sacagawea dollar is a one-dollar value circulating coin that was introduced in the year 2000. It is also called the golden dollar in the non-numismatic community because of its colour. The coin honours Sacagawea, a Shoshone Indian woman who was a guide and interpreter for the Lewis and Clark expedition of 1804. Glenna Goodacre designed the obverse of the coin and Thomas D. Rogers created the reverse. Sacagawea dollars are struck for circulation at the Philadelphia and Denver Mints, while Proofs are struck in San Francisco.

Saint

 

Slang for the Saint-Gaudens inspired double eagle struck from 1907 until 1933. (The 1933 issue is currently considered illegal to own as the government insists that none of this date was legally released.) This low relief copy of the Extremely High Relief and High Relief designs was the work of Chief Engraver Charles Barber.

Saint-Gaudens

 

Last name of Augustus Saint-Gaudens, the preeminent sculptor of the late nineteenth and early twentieth century. At the request of President Teddy Roosevelt, he redesigned the eagle and double eagle in 1907 although he died mid-production. Also, slang for the Liberty Head double eagle or Saint.

Saltwater Unc

 

A very deceptive term. Generally, a term to describe coins with a finely pitted surface, however, recent discoveries of coins that have been exposed to saltwater for over a hundred years has made this term inaccurate, if not obsolete. The sand, not the saltwater, likely does the pitting on gold and silver coins in the ocean. A better term for these coins would be sandblasted UNC or sand-damaged UNC’s.

San Francisco Mint

 

The United States branch Mint located in San Francisco, California that struck coins from 1854 until 1955. After closing as a Mint, it served as an assay office until it reopened as a coinage facility in 1965. This facility manufactures annual proof coin sets, manufactures silver proof coin sets and manufactures commemorative coins. This mint uses the “S” mintmark.

Satin Finish

Another of the experimental Proof surfaces used on U.S. gold coins after 1907. The dies were treated in some manner to create the silky surfaces imparted to the coins.

Satin Luster

Fine, silky lustre is seen on many business strike coins, especially copper and nickel issues. Almost no “cartwheel” effect is seen on coins with this type of lustre.

Scratch

A detracting line that is more severe than a hairline. The size of a coin determines the point at which a line ceases to be viewed as a hairline and instead is regarded a scratch; the larger the coin, the greater the tolerance. A heavy scratch may result in a coin not being graded by PCGS.

Screw Press

The first type of coining press used at the U.S. Mint. Invented by Italian craftsman Donato Bramante, this press had a fixed anvil (or lower) die, with the hammer (or upper) die being attached to a rod with screw-like threads. When weighted arms attached to the rod were rotated, the screw mechanism quickly moved the rod with the die downward, striking the planchet placed into the lower die. The struck coin then was ejected and the process was repeated.
