Abbasid Dirham?

It does indeed Petrus and thanks.

My problem is knowing whether the very small differences I feel there are to the inscription between 7 and 8 o'clock to the obverse are die quirks or differences to the date of issue ... similarly the double instead of single inner circle and missing symbol (ha) below the reverse script.

I have to say, I'm struggling with the Arabic. I can't even work out where the legends start and finish!

Nor do I know if it's the real deal. Though I can't see why anyone would copy what appear to be fairly common coins ..

Thanks Petrus. If I win it I surely will!

(My main interest is whether this coin might have circulated in Viking Britain. The date given by the seller is way out, but my feeling is that it's a 'possible'.

Such Dirhams are not infrequently found alongside Viking issue silver pennies. An early example of an internationally traded coin, just like the later Spanish-American 8 Real or Maria Theresa Thaler.)

Thanks Sap! A very helpful photo!

That would date it a little earlier than the British period, but that's not a problem as it may well have circulated in the Viking world. I'll do a bit more research if I win it!
