If a piece of silver is 7.78 gms or over it needs a hallmark, if it doesn't carry a hallmark you must call it "White metal" under that weight it's okay to call it silver or punch it .925, which is very interesting because a C.B.E, M.B.E and O.B.E's are all over the weight limit and they are not hallmarked and for the last 40 years I've described them as silver to St Jame's Palace, mmmmmmmmmmm I reckon the Queen is breaking the law !!!

But Agent 44 is correct I've just phoned Birmingham assay office to confirm.
