YEMEN. Gold Riyal, AH 1378 (1958). PCGS MS-63 Gold Shield.
Fr-8; KM-Y-G17.2. Variety without incuse Arabic number. Sparkling quality with few marks on either side and underlying evidence of what appears to be a flip-over double strike error that resulted from the coin being struck once and then a second time after the planchet had flipped over. RARE and highly desirable, this is only the second example seen by PCGS.
Estimate: $5000 - $8000
