Potosi, Bolivia, cob 8 reales, Philip III, assayer T, mintmark as

Potosi, Bolivia, cob 8 reales, Philip III, assayer T, mintmark as retrograde P ("q") over normal P, q over rotated q in king's name, quadrants of cross transposed (ca. 1620). S-P21; KM-10. 26.95 grams. Fascinating coin with mintmark appearing like the Greek letter "phi" and weird rendering of the king's name as qHYLYqVS (the q's punched over q's that were initially punched in upside-down) due to the die-engraver's misconception of what a P should look like (more incompetence than dyslexia), good full shield and cross-and-tressure despite some minor weak spots, non-toned VF.

Estimate: $250 - $375
