Prussia, 5 Mark, 1913-A (Berlin), PCGS MS64+

The common currency issues were generally ignored by collectors at the time.  Nobody much bothered to seek and set aside choice examples.  So when an example of the Crown-size 5-Mark in this quality turns up, it's something really special.

Beautifully struck with brilliant, booooming cartwheel lustre, this coin is a joy to behold.  Contact with other coins is at a minimum.  MS64+ can be considered a lofty grade for these humble coins, so don't under-estimate the considerable rarity.  Just look at the Pops: only 1 graded higher to date, despite a mintage of almost 2,000,000 pieces.
