friedsquid, well I put the note on a light table and then closely examined it with a high
intensity LED light. There "seems" to be a depression in the lower LEFT corner of the face and
a slight "hump" in the lower right of the reverse. The edges of the note in that area show no
signs of "disturbance". Is it a "fold", don't know.
I reviewed the grading standards of the IBNS (International Bank Note Society):
"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."
Maybe what we're observing is a counting fold. ?? Oh well, it is a nice note and the cost was quite reasonable. Thanks for your observations and comments.
