According to a post on the web site of the Türkmenistanyñ Merkezi Banky (Central Bank of Turkmenistan), new banknotes have been issued in the denominations of 1, 5, 10, and 20 manat. All of the notes appear to be dated 2012, bearing new signatures, and with a pearlescent stripe on back. The two larger denominations also appear to have SPARK patches on front. There’s no information on the fate of the 50- and 100-manat notes. As the largest denominations in Turkmenistan, one would assume they are in line for enhanced security features, too, but perhaps the bank still has sufficient stocks of the notes originally issued in 2009.
