Wilhelm I 20 Pfennig 1873-H AU53 PCGS, Darmstadt mint, KM5. Mintage: 54,000. An extremely rare mint for issue, and the second low-mintage 20 Pfennig of the period, this being one of only 5 certified between NGC and PCGS. The surfaces appear astonishingly luminous and free of marks for their smoky charcoal hue, sharper silver highlights granting a visual pop to the devices.
