Comments: Two misplaced digits can be found on Obverse 1. The most significant misplaced digit is the extra upright of a 1 digit in the base directly above the space between the 90 digits in the date. Dr. Tim Cook first pointed out this misplaced digit during 1999. A second misplaced digit is found between the top of the scroll end and the right gown fold. This misplaced digit is the upper section of a top loop belonging to the 8, 9 or 0 digits.
On Reverse A, the Medium S mintmark is tripled punched during an early die state. Repunching is visible on both the right and left sides of the mintmark. After striking coinage with the triple punched mintmarked reverse, we have evidence that the die was polished several times. In between the die polishing events, incremental coinage was struck once again with Obverse 1. Below are Obverse 1 and Reverse A images of a mint state example where the reverse has been polished at least once and removing all the repunching on the mintmark and some ribbon end details.
