A very nice piece, especially for this rare issue.
After a hiatus of more than a year from the scarce 1652 issue, the Vilnius mint is back to minting trojaks. This is an issue with a revised iconography, closer to Crown issues. It doesn't last long, however, as already in 1665, by order of the king, the mint is closed.
A variety with a star in front of the Pogo and the initials TLB.
Well minted, fleshy, with luster and uneven patina.
