"I came across a couple of links to the coinage produced by ISIS when it controlled large areas of Syria and Iraq; your links are the most authoritative I have found.

"Certainly the images shown in the second link correspond to what I know as the genuine issue, rather than the coins purporting to be trials (or more likely fantasies) as shown in this Wiki link:

"I have four examples of the 25 fils copper coin; these are struck on both thick and thin planchets. I obtained these a few years ago. Although I have attempted to complete the series and was briefly in touch by email with a contact claiming to have served in the US military in Iraq who said he had several coins, I have been unsuccessful.

"While I am aware of the controversy of collecting coins of a terrorist organisation such as ISIS, as historical numismatic artefacts I believe there is considerable value in recording and retaining examples for posterity.

"I'd be interested to know if you are aware of the two planchet types for the 25 fils coin."

I'm not aware of different planchet types. Do readers have any information about this?

In working on my consignment Stephen Album Rare Coins contacted the State Department and was given a green light to offer them. I know some people have been concerned about the terrorist connection, but those fears were just conjecture.

Nick added the following comments and images. Thank you! It's great to discover and document new varieties. This is how coin catalogs get written and updated. -Editor

"The types I have for the 25 fils are:

• Type I dated 1438 (2016/2017) weighing 20 grams. 2mm thick
• Type II dated 1438 (2016/2017) weighing 15 grams. 1.5 mm thick

"Both marked with their weight.

"I suspect Type I is a first issue, and Type II an economic second striking to save copper. Type I seems to have more wear than Type II. Both types were obtained in 2018."
