R.S.F.S.R. Proof Rouble 1922 ПЛ PR66 NGC, Leningrad mint, KM-Y84. Obv. National arms. Rev. Value in center of star with date below. A tone-free and stunningly reflective premium Gem of this important 20th century proof rouble, with light frost on the raised devices that produces just a hint of cameo appearance. Much finer than is typically encountered, and thus conditionally very rare for the type; currently tied with one other example for the finest certified at NGC of this P.V. Latishev "ПЛ" initialed variety.
Estimate: 8000-10000 USD
