Bright from polishing and unevenly thick (as made), somewhat flatly struck except for reverse legend (which shows a bold N over sideways N at the end of HISPANIARVN) but virtually no corrosion (hence choice for the assigned Grade), full 9 and bottoms of 16 of date (not mentioned on tag or certificate). Estimate: 1500 - 2250 USD Potosi, Bolivia, cob 8 reales, Philip II, assayer B (early 3rd period), Grade 2. All their COA records look very analog to me so that may be my only option. With Fisher tag and certificate 85A-140331, pedigreed to the RWB Reference Collection of Atocha dated cobs. Bold full shield and full cross despite moderate corrosion, bold full 9 of date. S-P21; KM-10; Cal-933. A. tocha Coin Grade. Based on my limited knowledge it is from the Mexican mint and appears to be from the correct time frame as other examples from the Atocha I have seen but I defer to the experts for confirmation. Sometimes you can't say exactly why a coin is phony, but you know it is by the "look".
