Perhaps Byzantine, since they have a lot of crosses. But I've never seen that specific design and dark color. It's in nice shape, whatever it is
I couldn`t find it anywhere. It is definetely not a button I bought this one in a lot from a specialized auction house.
This is a very cool coin and quite unusual to find any info on it if you don't know where to start. I found a page in Michael Mitchiner's World of Islam on page 328 under The Crusades, #'s 2420-2438. I was looking for something else and happened upon this page only a few days ago. The material before it was on the Crusades. Totally accidental my my brain remembered where to look as a result of your posting. It's lead: Mitchiner says: "A series of small Byzantine inspired lead coins." It has a star obverse, reverse is crossed crosses. Mitchiner goes on to say: "This small hoard of lead coins was brought to London bya Turkish dealer in 1975 along with sundry Byzantine and Isslamic copper coins from the Turkey-Syria region. Scatteered additional coins of the lead series have been seen since then in London." I have been collection Byzantine and related coinages for thirty years. I have never encountered on of these and would certainly grab it if I did see one. I hope you still have it. As far as value, only the coin gods know. It is certainly for the specialist. I hope this helps. I love puzzles like this.
