Undated Contemporary Counterfeit Halfpenny. George III English Type of 1770-1775—Flipover Double Struck—About Uncirculated.78.4 grains. A most perfect error coin, struck once and then flipped over with a quarter turn and struck again, obliterating any signs of a date on either side while creating the most incredible jumble of design motifs. The legends now read GEORGIVSBRITAN REX IA on both sides! Well centered, well struck and well preserved, this coins problem free iridescent brown surfaces are a delight to study.From the Sydney F. Martin Collection. Earlier ex Tom Rinaldo, April 2008.
