increase the accessibility of alternative coin cleaning
methods.

A major contribution to the group has
been the following glossary posted by Bob of Manor Antiques.
- A -
As --- a bronze coin.
Aes --- bronze.
Agonistic --- Relating to the games. This can be athletes in
action or an agonistic table with prizes and other accessories.
Anepigraphic --- a coin design with no legends. While many
coins have lost their legends due to wear, this term is applied only
to coins that never had a legend.
Antoninianus --- named after Caracalla (Mar. Aur. Antoninus),
who introduced the denomination in 215 A.D.; replacing the denarius,
and had twice the value (double denarius).
Apex --- conical cap. One of the sacrificial instruments
found on reverse types.
Argenteus --- a silver coin equal to a denarius, struck until
the time of Julian (361-363 A.D.). Latin for "of silver", or "made
of silver".
As (or Aes, plural: asses) --- Latin for "unit", originally
the name for a unit of weight (as the English pound), originally
divided into 12 ounces, or unciae, and the weight of it judged by
what could be reasonably supported in the hand of an outreached arm.
By the time of Augustus the as weighed 11 to 12 grams, the Roman
monetary system was based on this.
Aspergillum --- used to sprinkle water over an altar and/or
victim. One of the sacrificial instruments found on reverse types.
Augur --- a member of the college of augurs which originally
only included three members and was gradually expanded to sixteen.
These men were diviners whose duty it was to determine whether the
gods were in favor of a proposed action through the observation of
signs. These signs were often given by birds. Being a priest in the
college was a highly dignified post. The highest ranking members of
society which included members of the imperial family considered it
to be an honor and an advantage to be chosen as a member of this
college.
Aureus --- the standard gold coin. It was worth 25 denarii or
100 sesterii. The name means "Golden". Replaced by the solidus
during the time of Constantine the Great (307-337 A.D.).
- B -
Beaded Border --- many, perhaps most, ancient coin designs
enclosed the designs in a border of dots. It is unusual for a coin
to be well centered enough to show a complete border.
Bigatus --- the colloquial name for the denarius of the Roman
Republic depicting a biga (two-horsed chariot).
Billon --- an alloy of silver with copper.
- C -
Caduceus --- a wand or rod entwined at one end by two
serpents was an attribute of Mercury, the messenger god. The two
serpents represent prudence while wings sometimes added to the wand
were symbols of diligence, both qualities desired in trade and
commerce, of which Mercury was the patron deity. The caduceus is
often held by female deities such as Pax, Felicitas, and Concordia
in which case it is a symbol of peace and harmony.
Centenionalis --- from the Latin "centeni", (hundredth). A
late Roman denomination equal to 1/100th of a solidus.
Cippus --- a raised stone which is inscribed to preserve the
memory of an important event. These stones were usually small and
square in shape, used for both secular and religious purposes.
Cista Mystica --- a sacred basket used in Dionysiac rites,
always shown with the sacred serpent.
Cistophorus --- coins whose name is derived from a cista
mystica or mystical box used in the worship of the god Dionysus. The
term cistophorus was originally given to the person who carried this
box which housed the sacred serpent. The coins with this title were
struck in Asia Minor in recognition of feasts carried out in honor
of Dionysus and came to be a symbol for Asia. After Rome’s conquest
of Greece, names of Roman magistrates began to appear on them.
Cornucopiae --- horns filled with fruits, corn-ears, and
flowers is a recurring symbol on Roman coins pertaining to
abundance, fertility, and happiness. This symbol was sometimes used
by moneyers to refer to the abundance of things acquired through

of the coin in denarii of account.
Didrachm --- the two-drachma coin.
Die --- metal piece for striking coins, engraved with the
design in negative.
Diobol --- the two-obol coin.
Drachm(a) --- the basic denomination for most Greek coins,

one eighth of a denarius, or two asses.

important figure in consecration ceremonies where it was released
from the summit of a funeral pyre symbolizing the dead person?s soul
being carried up to heaven and therefore becoming a god
Electrum --- an alloy of gold and silver, either natural or
artificial.
Exergue --- the separate area of a coin below the ground-line
