<p>[QUOTE=&quot;J Dagger, post: 10135032, member: 10944&quot;]I swear there was a different purity with a proprietary name used in England in the 20th century. I am pretty sure it was .980 too. I know because I had a piece with the name on it I believe. It was an alloy more resistant to tarnish than others. That was the reason they used it for a bit from what I recall reading.&nbsp; I’m familiar with the .950/Britannia standard, I’m thinking of a different one. </p><p><br /></p><p>Japan did use decimal/numerical marks quite a bit. I’ve owned and/or handled countless pieces bearing them. They may have used character marks on domestic silver and they may have been on some export silver but they definitely also used numerical purity marks. There is almost never a literal decimal point (.) which is why I’m using numerical rather than decimal there.[/QUOTE]</p><p><br /></p>
