Currency Grading

GEM	A perfectly preserved note with full embossing, well centered and razor sharp corners.
UNC	Uncirculated notes have never been mishandled, corners are sharp without any evidence of rounding.
AU	About Uncirculated notes have minor handling, a bank counting fold at one corner or a very slight fold through the center, but not both. Paper is clean and corners are sharp. Cannot be creased, a crease being a hard fold that breaks the surface of the note.
XF	Extremely Fine notes have light handling. There can be 3 light folds or 1 strong crease. Paper is clean and firm with sharp corners.
VF	Very Fine notes have evidence of handling and wear. May have several folds. Paper may be dirty or smudged, but is still relatively crisp and not floppy.
FF	A Fine note shows circulation with many creases and wrinkles. Paper is not excessively dirty but may have some softness, there is no center hole from folding. Maybe even a staple hole or two with tiny nicks and tears on the edges.
VG	Very Good notes are well used but still intact. Tiny nicks and tears that extend into the design.
G	A Good note probably has graffiti, stains, dirt, holes, rips and tears. Rounded corners and not very attractive.
F	A Fair note is totally limp, heavily used and worn. Large pieces may be torn or missing. Parts of the note obscured by wear and dirt.
P	A Poor note has severe damage, a rag that may be taped together. Only used as a filler or when the note is the only one known to exist.
