Raid in a mint in Şahinbey
In its videos ISIL only showed the 1 and 5 Dinar coins and only computer drawings of the other denominations. On 7 October 2015, Turkish police raided a mint in Şahinbey, a city in the south-east of Turkey near the Syrian border (see map). 56 dies were seized. With these dies it was only possible to mint 1 and 5 dinar coins. 6 people were arrested, some of which were foreigners of an unspecified nationality.
The designs on the seized dies
match with the designs on the 1 and 5 dinar coins shown in ISIL footage. This leads me to believe that ISIL never minted the 10 Fulus-10 Dirhams coins and so that there are being sold many fantasy imitations that don't originate from ISIL at all. Furthermore there is a difference in the lettering between the 5 Dirham pieces that were minted at the mint in Şahinbey and the pieces that are being offered for sale by dealers.
