A very nice half-penny of the rare variety.
Coin well, evenly struck, fully legible, in a nice patina. Definitely above average for this denomination.
Type IV in Mark Poznanski's classification - the first with the head and royal sceptre dividing the inscription.
Variety with abbreviated notation of the ruler's name (KAZIMIR' instead of KAZIMIRI) and three points after REGIS (instead of the popular arrow). Rare.
Silver, diameter 21 mm, weight 1.69 g.
