Sometimes it is hard to understand experienced coin collectors when they are refering to different parts of a coin, as the terminology can be quite confusing for novices. In order to enhance your knowledge about coin collecting, you need to familiarise yourself with the following terms.

A small letter or letters that denote place of mintage or engraver

In time I will add pictures for the following elements too...
Bas Relief: Design elements raised within depressions in the field.
Border: Protective periphery either of radial lines or beads within the raised rim of a coin.
Conjoined: Joined together, usually used to describe two or more portraits, one behind the other.
Denomination: Face value of a coin or paper note; exact monetary value marked and considered legal tender.
Edge Lettering: Letters or designs made on the side edge of a coin. Most modern day coins have plain or reeded edges.
Exergue: The lower part of a coin or medal, usually divided from the field by a line (an exergual line) and often containing the date, mintmark or engraver's initial(s).
Face or Obverse side: The front of a coin or currency note, usually the side with signatures, honorary emblems, portraits, etc.
Face Value: The value of a coin or paper money as imprinted or marked on that unit.
Graining: The teeth at the edge of a coin.
Ground: The baseline on which figures or other parts of a coin's design stand.
Incuse: The design of a coin which has been impressed below the coin's surface. When the design is raised above the coin's surface it is said to he in relief.
Lettered Edge: The narrow edge of a coin bearing an inscription, found on some foreign and older United States coins.
Lettering: Any inscription or legend on any part of the coin, including the rim or edge, usully excluding lettering which forms the main design such as a cypher or monogram.
Milled Edge: A raised run around the outer surface of a coin. Not to be confused with the reeded or serrated narrow edge of the coin.
Plain Edge: The edge or outer border of a coin which is smooth and without any decoration.
Reeded Edge: The edge of a coin with grooved lines that run vertically around its perimeter. The edge found on all current United States coins other than cents and nickels.
