UNCIRCULATED (UNC):
A perfectly preserved note, never mishandled by the issuing authority, a bank teller, the public or a collector. Paper is clean and firm, without discoloration. Corners are sharp and square, without any evidence of rounding. (Rounded corners are often telltale sign of a cleaned or “doctored” note.) An uncirculated note will have its original natural sheen. NOTE: Some note issues are most often available with slight evidence of counting folds (creases). Also, French-printed notes usually have a sight ripple in the paper. Many collectors and dealers often refer to such a note as AU-UNC.
