COIN COLLECTOR WORDS

that start with the letter

" O "

oddity: - when something unusual happens to a coin it is sometimes called an oddity. Can be an "error" that was made at the mint, or something that was done to a coin after the minting of the coin.
obsolete: - a coin design or coins series that is no longer being produced.
obverse: - the front side of a coin. Usually the obverse side of a coin has the main design, date (year of issue), and sometimes a mintmark. Sometimes called the "heads" side of a coin because many coins have a person's portrait or head design on the obverse. The back of the coin is called the reverse.
off center , or off-center: - describes the way a coin was struck by the printing dies. If the coin was not placed properly and the dies strike it off center then parts of the design will be missing from the coin. Sometimes an off-center coin will have part of the blank planchlet showing and part of the coin design showing.
original roll: - a group of coins that were wrapped in paper wrappers at the time of their production. In early days coins were shipped to banks in cloth bags or kegs. Sometimes later they were shipped in rolls. Silver coins stored in rolls will often have toning on and near the edges but not in the center. Some coins stored in rolls will have fewer marks than those stored or transported in bags or kegs. The number of coins in a roll may vary by denomination and time of issuance. Typically there are 50 cents in a roll, 40 nickels, 50 dimes, 40 quarters, 20 halves, 20 silver and Eisenhower dollars, and sometimes 25 SBA or Sacajewea dollars.
ounce: - form of measuring weight. The troy ounce that is used for weighing precious metals is different from the regular grocery store ounce. Click here to read more about troy ounces.
overlapped edge lettering error: - a Presidential dollar coin that shows double edge letters on the side. Presidential $ coins have the date, mintmark, and US motto's impressed into the coin's edge. During production, when accidentally run through an edge lettering machine twice a coin will show double lettering on the side. "Overlapped" edge lettering means the error letters are facing the same direction as the first impression of the letters. See "inverted edge lettering" for and explanation of upside down edge lettering.
over strike or overstrike: - a coin that instead of being struck on a blank planchlet was accidentally struck on a previously struck coin. The result is the coin design pressed into the blank coin planchet twice. In rare occurrences an overstrike can be one type of coin struck over another type of coin. For example, a cent design struck on the top of a dime. This type of coin error is often somewhat scarce or rare.
