I am coming across quite a few unusual formations below the top silver, from these 3 pictures that go from one side to another of an area between engraved lines. You will notice that the silver above is either worn away or broke away, this is revealing something below which has a shape and depth, st...

Jag, Pleased you like all the references, nice to have a bit more insight about antique silver. It's not the iridium content that would nail it as you say, it's Indium which is the signature for Potosi silver, not prepared to have such a big sample taken off the button for a ICP-EOS test which I loo...

As I mentioned in my previous post, some flakes of silver had come off due to the engraver I thought, well it seems the silversmith has done something weird. There is this one button I have been focused on because of the silver breaking off, this reveals silver below which is tarnished through age a...

Well done to all involved with this site, good helpful people always on hand, the site will be here for a long time as people always need information

All the best.

Thought I would show you the pictures where the engraver had lifted off the flakes of the surface, it reveals the cracks underneath which you can follow across the button. http://img142.imagevenue.com/loc43/th_570822526_MonFeb1622_25_14_122_43lo.jpg http://img181.imagevenue.com/loc337/th_570821231_M...

Jag, Thought I would post this link regarding Potosi silver, knew I had it somewhere on my computer. https://books.google.co.uk/books?id=KYx4AAAAQBAJ&pg=PA388&lpg=PA388&dq=gold+content+in+potosi+silver&source=bl&ots=6P8u7BKeak&sig=w7F8AhJ5yGHAGExHI3sNFZRpexA&hl=en&sa=...

Jag, You wrote:- But I did read the pages that are there, and it seems to me that when it comes to American silver, that the silver content will typically not be that useful for dating purposes. The reference says "Spanish coins remained the dominant source of silver for American silversmiths i...

Jag, Regarding your last sentence, that is a good rule of thumb to use, be suspicious of antique silver with (no gold) in? However, you cannot rule it out just on this finding. The tests carried out on these items were ppt, as I mentioned before, Spanish coins/cobs from the mine of Potosi in Bolivia...

Hi Scorpio, When I have a piece that is rubbed like yours, I take a few pictures and then in my photoshop software I turn the picture to a negative only, I don't do anything else to it. On many occasions this has helped me out, take a few pictures of different angles and then one face on, it normall...

Hi to all, Looking for some info regarding other inserts for George I casters, I know of later inserts being made for earlier casters, what I would like to know is there others around that have the mark of the maker to match the caster. Up till now I have not being able to locate any, any informatio...

Hi Trev,

These are English, made in London in 1717 by Thomas Langford I.
Although I did buy them from America, so it's possible that they could be of an American crest? To be fair, I have checked this line of enquiry as much as I can without any joy.

Hoping someone may recognise them

Regards

Steve

Hi, Would anyone recognise the crest on this caster, Lions/Bears gamb erased holding two Ostrich plumes, the torse is usually a twisted cloth I think, this looks like a ermine decoration, of course I await to be shot down here. Any information would be gratefully received, I have found other crests ...

Have now received all the assay results today, these assay results prove they are not English in manufacture, extremely consistent with American antique silver assay results which had XRF carried out on them. The buttons that have no gold in them could easily be from melted down silver Spanish coins...

Hi Oel,

Here is the picture of the fronts as requested



Best

Steve

Hi Oel, Did you just attach the line about the fronts of the buttons? It was not there before when I read your post, unless I am going daft!!! The buttons are just plain fronted, no engraved marks/pictures, absolutely clean as a whistle, will have to upload a picture to another site first before I c...

Hi Oel,

You are spot on there, I cannot disagree with what you have posted, thank you very much for the information, I shall now read up on this fellow

All the best

Steve

Hi Oel,

Thanks for your input, unfortunately you will see the shield/cartouche is different, also the marks within the shield is different from the lions you mentioned.

Regards,

Steve

Hi to all, These are the other set of buttons which I am researching at the moment, these were sold to me as pewter buttons, they are actually silver. So far for the I.K I have come across two possible candidates, James Kendall from Wilmington, Delaware, the other possible candidate could be Joseph ...

Jag,

sorry missed the bit you first asked about, I am charged £12.50 per button, roughly $19.00 I suppose per button.
