Germany 1877-A 1 Pfennig, KM-1, PCGS MS64RB, RARE DATE.  This rare date is listed at $1,000 in MS63 in the Standard Catalog of World Coins and "LP" in Muenzen-Revue (liebhaberpreis means the price is speculative because of the rarity of the coin).  This example has just the slightest mellowing of the original, full red color.  A small carbon spot (inactive) appears on the right side of the reverse.  Even in AU, this date lists at $350 and in MS60 at $800.  A great opportunity to add this rare date to your collection in Set Registry quality.
