I have found an article, which tells abot this coin:
Local Coinage and Civic Identity in
Roman North Africa pages 12-13
"The semisses are particularly interesting, as they were minted at the
same size as the
asses, but then purposefully cut in half, with an
obverse and
reverse design that was a mirror image, giving both halves the same designs.
This is an unusual design for semisses, and it is uncertain why
Carthage chose to
mint them in this way, as well as why they did not
mint them in the same manner
later on during the reign of
Tiberius."
this coin could be struck with die with cutter in the middle
How such die with cutter could work? Cut and strike at the same time?
Yes.
Why not accept the simplest solution: coins were normally struck and THEN cut.
I don't reject that, but all this coins were cut in the same place - on the middle from 12 to 6 hour and all leters are full visable. When you compare the cut edge of
RPC 749, 750, 751 and my coin, you can see that all this coins were cut from
obverse, not from
reverse. If the cutting process was made after coin was struck, some of this semisses should have deficiences in
legend, or should be cut in wrong place or cuting could be started from
reverse, because human is not a machine and can make mistakes...
