This 8-1/2" serving spoon has Swedish hallmarks and is monogrammed on the back with "Minne for 11 Ars Trogen Tjenst" which, according to Google Translate, means "Memory for 11 years of faithful service."

According to silvercollection.it, the 3 crowns inside a trefoil indicates purity of at least .800. Is there any way of knowing the exact silver content from the marks? And according to the same website, the trefoil mark was begun in 1901, but the date code of "D6" indicates a manufacture date of 1882. Also, I cannot find the makers mark of "JGH". Any Swedish silver experts out there?

Thanks,
Dave

Johan Gustav Hentzell, Kalmar. The shape of the three crowns mark has varied a lot and I guess it was just standardized in 1901. Anyway D6=1882 is the correct date.

The Swedish control mark (three crowns) mark is on a horizontally-ribbed trefoil shield. The mark is also called cat's paw and was implemented in 1. January 1754. The mark has a few variations in size. The Swedish minimum silver fineness could be 800 but is usually 830/1000.
The model's name is "Palmes Swedois and/or Old French". In Sweden the model is commonly called franska liljan (French lily). BTW, it is an ordinary sized table spoon. Spoons were bigger in those days.
The year 1901 mentioned in "SilverCollection" is incorrect. The correct date and year is mentioned above. Anyway, in 1913 a new mark was implemented for imported silver goods. It was the same three crowns but the shield was oval (elliptic).
