PROOF: Describes a type of coin, not a condition or grade. Such
coins are specially struck collectors pieces not intended for
circulation. Highly polished dies and blanks are used in their
manufacture so that they have a mirror-like finish when struck. They are
individually handled during production. Many proof coins have a frosted
relief, the design having been treated with acid or sand blasted so that
it has a matt finish to make it stand out against the highly polished
field surrounding it. Some proof coins have an all over matt finish
although this is not usual with Australian coins.
FDC (Fleur de coin): This is a French term
which literally means: "Flower of the Die". It describes a coin
in the highest state of preservation. It can be used with PROOF coins
exclusively struck for collectors, or coins produced for normal
circulation. The strike should be faultless and well-centred. Design
details will be razor-sharp. The surface of the coins and the rim will
not show and Detracting Marks, and full fresh Mint Lustre must be
present. There is outstanding Eye Appeal. Silver coins may feature and
attractive Patina or Toning. Bronze coins must be virtually fully
Brilliant.
GEM UNCIRCULATED: Far more often than not, this
will be the highest grade a collector can realistically expect to
encounter, as opposed to the above-mentioned "super coins" referred to as
FDC. A "GEM" uncirculated coin will be almost faultless with a strong,
but not necessarily absolutely perfect strike. The design may show just
a hint of die-wear but such wear should be minimal. Detracting Marks are
of a highly insignificant nature. Virtually Full Lustre or Mint Bloom
will be evident. Patina or toning may be present on both silver or
bronze coins. Strong Eye Appeal is present. With bronze coins, the
degree of Brilliance remaining may have a significant influence on the
value of the coin, but not its grade. It is unusual to find a GEM grade
bronze coin that has fully toned. Paradoxically, toning, (or lack of
Brilliance) is less acceptable to collectors on bronze coins than an
attractive tone (Patina) on a GEM grade silver coin. To express the
amount of Brilliance remaining on a bronze coin, some dealers will use a
"%" as an indicator after the grade. Thus, GEM - 50%B (or 50%
Brilliance) refers to a coin retaining half its Brilliance.
CHU (Choice Uncirculated): Sometimes
abbreviated to CHU. Describes a fairly well struck coin but some
weakness in this area is acceptable. A CHU coin will be free of any
significant Detracting Marks and still retain a considerable degree of
Mint Lustre. Pleasant Eye Appeal is present.
UNC (Uncirculated - Typical): As the name would imply, a coin which has not been circulated in the commercial sense and
therefore shows no wear. It may however have been struck from a die
nearing the end of its useful life, and not all of the intricate details
of the design may be fully formed on the coin. Moderate but not
excessive Detracting Marks from the production process may be evident in
the fields and on the rim. Fairly attractive Eye Appeal should be
present. Footnote: Detracting Marks or other major imperfections must
either be mentioned in addition to the grade, or if reasonable, the
grade itself should be lowered into the EF range, to be in keeping with
the values given in this guide.
aUNC Almost Uncirculated: Similar to above but
with faint traces of wear on the highest points of the design. The coin
still shows a reasonable degree of lustre. Coins in aUNC condition might
even have eye appeal more than uncirculated coins as they might be a
very sharp strike and have minimal bag marks despite showing very minor
traces of having been handled or circulated.
EF Extremely Fine: Generally speaking, this
grade describes a coin which shows some slight wear that is barely
noticeable to the naked eye. However care should be taken to give due
consideration to the striking of the coin in the first place. Be careful
not to confuse a soft strike with what might otherwise appear to be
wear.
VF Very Fine: A coin in this grade will show
distinct signs of wear which could not possibly be due to a soft or weak
strike. Most of the lustre will have disappeared and the high points of the
coin will be completely missing. Some very slight rim damage may be
present in the form of tiny indentations (as opposed to significant
nicks). Overall though, the coin should still be generally pleasing to
the eye with most of the major detail still quite sharp.
F Fine: By now the coin exhibits extensive
evidence of having been circulated. The general design is easy to
recognise but most of the significant parts of the design have worn
away.
VG: Very Good: A rather misleading term to
describe a coin which is in anything but in "Very Good" condition. In
fact the entire surface of the coin is practically devoid of significant
detail although the basic design and date will still be readable.
