For something to be designated
in uncirculated condition, as the name suggests, it must show
no signs of circulation. This does not mean that the note is
perfect. An Uncirculated note can have problems such as flicks,
counting creases, cutting cups, printer ink smears, band marks,
miss-aligned printing, and imperfect cutting.
These problems, henceforth known as imperfections, happen within
the printing and administrative process of making the note.
Because of their frequent occurrence, an allowance has been
made for their existence which determines the following degrees
of UNC. Every degree of UNC is a clean, crisp, and note with
the firmness of the paper completely in tact.
