Thank you Joel Shafer for the image scans. Joel cautions scans can be misleading as far as accurate grading is concerned (with either over or under grading, although a scan usually inflates the grade of a note).
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.
