hmmm.. prolly .... on first guess ...but not sure 1645-1652 ... will check my DB

What you have is a Potosi minted 2R. The assayer is Juan Ximenez de Tapia (T). The trouble with giving an exact date is that he served as assayer off and on throughout the early history of the Potosi mint. The latest he served was 1648.

Further study of the devices might be able to nail down a specific time period of his numerous service periods. As I look closely and compare characteristics, I will give my best guess as from the period 1629 - 1639.

Yes, Tapia actually had three tenures as assayer (give or take a year or two) 1st: 1618-1623; 2nd: 1627-1639; and 3rd: 1644-1648. He was the assayer for both Felipe III and IV. What makes the ID more difficult is that F III used at least 5 different "Coats of Arms" and F IV also used at least 5 different Coats of Arms. In my next life, I may study those differences.
Don.....
