RR-, Sigismund III Vasa Half-track without the second digit of the date, R3

A rare crown half-tone without the second digit of the date. Most likely, the stamp stock was prepared earlier leaving only the second digit of the date to be struck. Later, in a hurry, the finished stamp was used forgetting the absence of the last digit of the annual date. A rare and very interesting coin showing the details of the organization of the mint workshop in the 17th century.
