Very rare, first vintage half-penny of King Sigismund Augustus.
Type with the date, and the King's titulature (SIGIS AVG REX...) placed on the page with the Pogon.
Variety with legends ending in L * / LITVA (triangle).
The oldest type of Pogo and Eagle appearing on this denomination.
Its rarity is well illustrated by Tyszkiewicz's price list, which valued it at 30 mk, and by the next one, when the issue started on a large scale, at only 1 mk.
