Correction: maker's name is spelled SISINO, not SISNIO. Sorry about that.

Napoli is correct; this mark was used there from 1832 to 1873. The bust is that of Partenope, mythological queen of Naples. "8" is the standard, and stood for .833. (Standards 1-6 were for gold; the only silver standards were 7 [.916] and 8 [.833].) The "N" stands not for Naples ...

Essentially, yes, pseudo marks are fake marks. They were used to "enhance" the appearance of reproduction styles, primarily by the silver manufacturers in Hanau, Germany but also well-documented in the Netherlands. The mark on the right - GR, crowned - is the actual manufacturer's mark, at...

OK; here are the marks from Brault-Lerch which I think are those on your spoon: http://www.blakstone.com/BL_21_83_153.jpg And, for comparison: Brault-Lerch #20, the city mark in use ca. 1737 — 1740 . . . http://www.blakstone.com/BL_20.jpg Brault-Lerch #22, the city mark in use after 1777 (note the f...

Is Brault-Lerch #21 illustrated in Tardy or in Beuque? Could you give the correspondence in these books? Not really, no. The last mark on the top row of Tardy, p. 144, identified as “1730”, is close, but it’s also close to Brault-Lerch #20, the mint mark in use ca. 1737- ca. 1740, and not an exact ...

Looks like 1810 with the maker Johann Michael Bettle (master 1752, died after 1795; Seling #2414). That seems a little odd to me though: could a master in 1752 still be working 58 years later?. Good news, though. If anyone is interested (and has several hundred dollars to spare!) Helmut Seling's Die...

According to Brault-Lerch’s “Orfèvres de Franche-Comté” (Geneva: Librairie Droz, 1976), which has an exhaustive survey of Besançon marks, Beuque and Tardy are both in error. Your first mark, the double “C’s”, corresponds to Brault-Lerch #21, the Besançon mint-mark in use ca. 1745 to 1777. (It is...

I think the arms depict the heraldic device known as "the pelican in her piety", i.e. piercing her breast to feed her young on her own blood. In addition to the offical seal my native state of Louisiana in the U.S. (which the button is of course not from), the only civic arms with this dev...

There is no hammer and sickle mark. I have never seen Soviet gold or silver lacking that mark. The "hammer & sickle" mark was not introduced in the USSR until 1958. Before that, from 1927, this "worker's head" mark - there is a hammer at the base of the neck - was used. It i...

Soviet era companies had dreadfully unimaginative names. This is the mark of the Tallinn Jewelry Manufactory (more or less) for 1957. (The last digit gives the year.)

The mark is for 15 Lot silver (15/16 or .938, near sterling) used by the Austro-Hungarian Empire 1807-1866, with the date here in the 1840s. (The upper left digit is a one, and the lower right will give you the exact year - 184?.) The letter "B" at the top was the code for the assay office...

While the knife blades are German (Solingen is famous world-wide for its knives) the silver mark on the left is Hungarian, in use 1937-1965, and I think for the 3rd standard of .800 (the mark is blurry and upside down).

Grodno/Hrodna was part of the Duchy of Lithuania in the Polish-Lithuanian Commonwealth until the final partition of Poland in 1795 gave control of the city to Imperial Russia. There's no record of any Russian assayer there until the 1820s, and no known Imperial Russian hallmarks with the Grodno city...

Well, I'll be Dahmed. That's it: Jacob Diedrich Dahm (also Dam, Damm, Dann and - in Lithuanian - Jakobus Dydrichas Damas) of Grodno, Lithuania. Lietuvos Auksakalyste, XV-XIX amzius , the bible on Lithuanian silver, has several examples of the mark, and it definitely reads "DAHM". My Lithua...

The marks are pseudo-marks used by the Hanau, Germany firm of Ludwig Neresheimer & Co., which was founded in 1890. I think your cup probably dates from the first quarter of the 20th century.

Top to bottom, the marks are: 1) a helmeted head (inverted in the photo): the Paris décharge (discharge) mark of tax farmer Henri Clavel for small silver or gold articles in use 13 Jul 1780-31 Aug 1782. 2) "A", crowned: the Paris charge mark of tax farmer Henri Clavel for large silver art...

Bruckmann is the manufacturer, and Sanktjohannser is the retailer (who was located in Munich, if memory serves me.)

See Otto Wolter on this page.

I'm sure Bahner can confirm or expound, but I think it's Oskar Haegele of Schwäbisch-Gmünd.

It's César Tonnelier, working at 7 rue de Cimetière-St.-Nicolas, 1845-1859, and 325 boulevard St.-Martin, 1859-1882. He was succeeded by (his son?) Paul Tonnelier, 1882-1889.
