I can't make heads or tails out of this thing. I've used a loupe. I've taken pictures of them and played with them digitally, altering colors and lighting and shadows and every other setting I can think of to try and see the hallmarks better.
More than likely it's just that I'm just not knowledgeable enough in hallmarks to identify them.
The lion is plainly evident, but I can't even be sure what the letter is on the right. I've compared it to the date charts for London, Birmingham, Chester, Exeter, Newcastle, Sheffield, and York. I'm thinking that it might be Chester 1747, but I'm far from confident.
As for the other two, I got nothing. I think they're worn, which would actually work towards my 1747 theory. A newer piece wouldn't be as worn...
Here's a pic of the front and back, plus five more pics of the hallmarks up close, taken different ways or with different filters.
If someone could suggest a better way to capture the hallmarks, I'd be most appreciative :)
