Light 60 with the '2 o Quedlinburg' overprint, mint never hinged, flawless condition, certificate by Dr. Kalb BPP. Very few examples exist with this overprint. The Michel price is not applicable to this overprint on the light 60 Pfennig; it applies to the more common '2 o Koethen' overprint. Recent auction results for the latter were around 2000,-!
