PERU, Lima, pillar 1 real, Ferdinand VI, 1756/5 JM, mintmark not dotted, with stops in shield-side legend, unique, ex-O'Brien. Yonaka-unl; Cal-155; KM-unl (52 for type). 3.38 grams. While for variety this appears to be an unlisted muling of Yonaka-L1.56 shield side with Yonaka-L1.56a pillars side, with even bolder overdate, in fact neither side matches the dies shown in Yonaka, and we have to assume it is unique. XF with very light toning including blue tones near top, cleaned long ago. Pedigreed to the John O'Brien Collection, with his tag.
