3 Groats - Sigismund II Augustus Monogram, no shield reverse

The "no shield" reverse on this issue reflects an administrative shift in how Lithuanian coinage was distinguished from Polish Crown issues during Sigismund Augustus's prolonged push toward political union — a union that would not formally materialize until the Union of Lublin in 1569. The Vilnius mint was producing trojaks in considerable volume through the early 1560s, and die combinations from this period are numerous enough that Kopicki catalogued multiple distinct varieties for the 1562 date alone.

Gumowski's classification separates this type specifically on the absence of the Pahonia shield, making attribution straightforward when the reverse is intact.
