It has to be after 1820/21 (because the leopard has no crown) and before 1837 (when the duty mark changed to Victoria), so it must be 1828 as @sixgun says.

Yeah, as @stefffana said, comedy hallmarks!

If you don't care if it's not coins, silver salvers on ebay go under spot occasionally. Only today a 10oz silver salver went for £150 with free postage, and with spot at £18, it's worth £166. A few months back some lucky soul got a silver salver weighing nearly a kilo for £295! Other antique silver that normally sells around spot is holloware (bowls, tea pots, etc) and flatware (spoons & forks), the newer stuff will be the cheapest coz people collect the old stuff! You'll have to invest some time traipsing round ebay but it could well be worth it.

Yes I can. Pity it's not silver 😁

Well you learn something new everyday, thanks for that info @stefffana, I've only ever dealt in British silver, so my knowledge of foreign silver is pretty slim. You're definately the man for foreign silver! Mobius

Hi, The item(s) marked '90' could well be foreign 90% silver. The other items are plated, on the bottom picture you can see 'EP' which stands for Electro Plated.

Hi, the 958 is indeed the silver fineness, it's a Britannia Standard silver mark, the next mark is the import mark for London and then the date letter 'A' for 1975. I can't help with the makers mark unfortunately, it's always hard to get info on modern makers. Mobius.

I agree with @sixgun, that is the date letter 'D' for 1839 (London). The other marks are the Lion Passant and a Duty Mark.

Yeah, we love it.

The makers mark is impossible to make out but the other marks look French to me. The style is Georgian (1820 ish) but could obviously have been made later. @stefffana might be able to shed more light on it.

Well, you see Sheffield and JD on some silver and you think James Dixon. But he died in 1852. Or did he....

Yep, according to Silver Makers Marks, JD is err... JD! Big help. It's too modern for any of my reference books too I'm afraid.

Hi, The maker is/are Samuel Hayne & Dudley Cater. Year is 1836. Mobius

The maker is probably Joseph Mappin, but the date is more difficult, if it is Joseph Mappin, it's possibly from around the 1840's, before the formation of Mappin Brothers (and later Mappin and Webb). Hope this helps.

Hi, These marks are 'pseudo-hallmarks', meant to resemble real hallmarks at a glance, which unfortunately makes your sugar tongues electro-plated and not silver. Mobius.
