Shout-Out To The Oz Contingent... 1943 Florin

Heavy contact at 5 o'clock on the obverse (the I and D) have me caught between F and VF.

Australian collectors do not use the 70 point Sheldon scale for grading.

Australian Grading is done using this system

GRADING Of Australian Coins
PROOF
Describes a type of coin, not a grade. Proof coins are not minted for circulation, they are collector issues. They have a mirror-like finish which is a result of the highly polished dies and blanks used in their manufacture. The design on many proof coins have been treated with acid or sand blasted to give them a matt finish which make it stand out against the highly polished background. This is called frosted relief.

FDC (Fleur De Coin or Flower of the die)
A perfect coin. A sharp strike with fully formed detail. There can be no detracting or contact marks. Full mint lustre must be present. Attractive toning is acceptable on silver coins only. Eye appeal should be brilliant.

GEM (Gem Uncirculated)
A few insignificant detracting marks may be just visible to the naked eye. Strong but not perfect strike. Almost full mint lustre should be present. Attractive toning may be present. Eye appeal should be very high.

CHOICE (Choice Uncirculated)
Should be well struck with only minor detail missing from the high points of the design. Detracting marks should be very minor and should not attract your attention. Mint Lustre should be apparent. Attractive toning may be present. Eye appeal should be excellent.

UNC (Uncirculated)
As the term implies, a coin which has not been circulated in the commercial sense. The coin may have a flat strike caused by excessive use of the dies when minting. Detracting marks received during minting are acceptable. However if the marks are not minor or they detract from the coins appearance they need to be mentioned and taken into account when grading. Eye appeal should be very nice.

aUNC (almost Uncirculated)
Similar to uncirculated but with faint traces of wear to the high points of the design. Detracting marks are acceptable as long as they are not too bad. Some lustre should still be visible. Eye appeal should be very nice.

gEF (good Extremely Fine)
Coin should have visible light wear. Detracting marks from circulation handling will be visible however they will still be of a very minor nature. Some lustre may still be evident. Eye appeal should be nice.

EF (Extremely Fine)
Coin should have easily visible light wear. Be careful not to confuse a weak strike with light wear. GV coins centre pearls should be separate. More detracting marks will be evident but should not be serious. Lustre may still be present and eye appeal nice.

aEF (almost Extremely Fine)
Coin should have easily visible wear and a few more detracting marks than an EF coin, GV coins should have strong centre pearls. The overall condition and eye appeal should still be quite nice. Lustre may still be present.

gVF (good Very Fine)
Obvious wear, obvious but not serious contact marks. GV coins centre pearls may be merging together. Eye appeal should be very good.

VF (Very Fine)
Coin will show obvious wear and all high points of the design will be gone. Detracting marks in keeping with expectati ons for wear including several minor edge nicks and dents. Major detail should still be good with GV coins having a full outline of the centre diamond. Coin may still have some lustre. Eye appeal should be very good.

F (Fine)
Coin will have extensive wear. The major design will be easily recognisable but most of the detail will have worn flat. There will be more detracting mark and nicks / dents.

VG (Very Good)
Up to almost 3/4 of the detail of the coin will be missing. There will be lots of flat spots where the high detail used to be. Overall design of the coin including wording and date should be readable.
