Hi All,
Would really appreciate it if someone could help to identify these 3 large copper medallions. Stored in a presentation case as per the images.


The items are all pure copper.
They each have a diameter of 80 mm.
Weight in grams for no. 1 is 253.5, no. 2 is 313.1 and no. 3 is 297.2
Have tried Google attempting to ID without any joy.
Would really be happy if someone can shed some light with regards these items.
Also any idea on value will be welcome as well.
Each item is marked - PRIMATESTA.
Looking forward to your responses.
Thanks in advance once again.
Mike.
