Real gaznavid dirham? [solved]

is this how a gaznavid dirhams rim looks (cast) @Vic65

I have a very lage number of these collected over the years, the edge varies a lot, some are rough all around or partially and a lot more have smooth edges typical of hand struck silver.  If cast then there would be evidence on the flan as well and it looks o.k to me as best l can tell from your photo
