Mexico City mint, KM160, Onza-1253 (dot between ET and IND on the obverse). Choice Mint State with semi-prooflike fields, sharply rendered details and a handful of surface abrasions preventing the Gem technical designation. A wonderful representative of this imaginary bust issue, extremely rare and immensely desirable in this quality. Better struck than the Rudman coin (also graded MS64 NGC) and the finest example seen by us, thus truly a wonder type coin that would grace the most refined cabinet.
