The third issue of notes (the second by the Bahrain Monetary Agency) with the same denominations of to 20 dinars was released in March 1993. This series was upgraded during 1998 with various modifications to colour and security features. However, a fake order for banknotes had recently been placed with the Argentinian printer Ciccone Calcografica who did not verify it with the legitimate authorities in Bahrain and obtained genuine banknote paper from Arjo Wiggins to print over 7 million unauthorised replicas of the 20-dinar note (of the 1993 design), equivalent to US$365 million. These differed from genuine notes in two respects: different background shading to the Arabic name of the Bahrain Monetary Agency, and a large gap between the two Arabic letters in the horizontal serial number.
