KM-127; Bit-3816. The tynf, a denomination popular in Poland and Lithuania, was equal to twelve kopeks. We have sold a few of these before (2016 ANA sale, lot 21382; 2016 NYINC sale, lot 41364; 2013 ANA sale, 13335) but none of this variety and this one is finer than the others. Lustrous and fully struck with a small unobtrusive obverse planchet flaw. A worthy addition for even the most advanced collection. NGC MS-63.
