An original slightly "grubby" coin with a touch of light greenish-gray color on the Reverse.  Tough in this grade and perhaps a bit undervalued.  Similar certified Population levels in the grade to the much lower Mintage 1921-S: 70 coins at PCGS for the '23-S versus 53 for the '21-S, and the same 34 coins for both dates at NGC.  This despite the value encouraging submission of anything close.  Considering that the '21-S is about 3-4 times the value in the grade, those numbers seem a bit funny to me.

PCGS 6586.40/59026922
