90% 'Sterling' mark

These marks are on an ashtray that has a Hong Kong Silver Trade Dollar (or a coin that purports to be such) set into the centre. Does the mark in fact indicate 900 silver and is the coin genuine? Thank you.

Hi,
90% is close to sterling (.925 or 92.5%) silver fineness.
1930 was minted in London (no mint mark) and Bombay (B), over 6 million and 10 million respectively.
Anyway, there is no numismatic value in the coin.
Regards

Thanks AG2012, There is a B in the central prong of Britannia's trident so a Bombay minted coin. Presumably the JAW is for a Chinese or Hong Kong silversmith?
