20 pennies 1923, Occupation, minted

Zinc coins of the General Government in light blue color not covered with patina, without intergranular corrosion manifesting itself in a rough surface are coins unheard of on the market, and pieces appearing on the market both with and without grading are single pieces. Grading companies, as yet, do not distinguish colors for zinc coins (as they do for copper and bronze), which generally belong to short series of small war issues and therefore remain undervalued. Light blue zinc coins are to coins with graphite patina what copper RDs are to BN. The offered mint piece, on most surfaces in light blue. A coin for the best collections.
