When was sterling silver first marked as 925?
In 1904 the Silver had to be marked with the .925 in an oval shape, with the Brittania Standard silver mark being .9584 in an oval shape. In 1973, the new Hallmarking Act dropped the decimal ( . ) from infront of the 925 and the font type changed a little, and in the case of the brittania Standard, dropped the decimal ( . ) and did away with the 4 at the end (although the diminution in value did not change) so that it became 958 in an oval.
