Blackstone is right, but I would have no doubts about the dates. The 800 mark, in fact, is inscribed in an oval that has the dimensions provided by the official gazette of 17/8/1971.

It should be noted that at the time of the entry into force of the application regulation, the Mint was faced with an enormous commitment : to replace the old punches it had to produce more than 2800 molds each of which could be requested in 4 different sizes,. In addition, he had to manufacture the mold for new companies. There have been enormous delays. Probably Mr. Loro did not want to wait for the delivery of his molds and made an old-fashioned temporary punch for himself. Maybe not entirely legal, but understandable.
Just my opinion.
Amena
