Can anyone identify this mark? I have tried google but im not really getting anywhere, this is on a chain.
Sure it's not 999 upside down? Would think most chains would be 925. Could be a design number like some flatware - see http://www.alastaircrawford.com/php_uploads/hallmarks.php
I have just double checked and its 686 AR for sure, But the strange thing is there is no marks for purity , no 925 stamp or nothing thats the only stamp on it.
cant find any other marks at all, but thank you that looks like it so might be able to track a maker down for it, luckily it only weighs about 20grams so not a massive loss if it isn't silver but i think it probably is.
Ah! Google "Arezzo Silver Hallmark" and there are examples. http://www.silvercollection.it/SILVERSMITHSAR.html lists the first 120. So it's a makers mark, not a fineness. Another example:
