1893, 8¢ Columbian, printed on both sides, block of 4, o.g., hinge remnant at top, never hinged at bottom, clear impressions on reverse, bright color, F.-V.F., a rare variety and the only known multiple of this variety, due to the controversy of whether it is a true error, it is being offered on its own merits; with 1978 P.F. certificate stating "printed on both sides…it is a genuine variety". Scott No. 236 var.  Estimate $1,000 - 1,500. This is the only multiple available of this variety discovered on one sheet in the 1970's. It has been argued by some that the impression on the reverse is a secondary or right reading offset while others believe it must be a true printed on both sides variety. $0 (Image)
