Watch List notes:

Potosi, Bolivia, cob 8 reales, 1617M, very choice full date. S-P19; KM-10; CT-129. 27.08 grams. Attractively old-toned XF with choice full shield and cross, but best feature is the 100% full and bold date in oversized digits, apparently engraved in the die IN LIEU OF the usual dotted border, which ends right before and begins right after the date, so perhaps one of the earliest versions of this first dated issue.

Estimate: $600
