They are lead not pewter and solid lead.
They are 15th or 16th century. Please correct.

These plates are solid lead. They were not used as chargers. The knife marks are proof of that. There are very few lead plates that exist now. But there are a few lead chalices. I have pewter bowls and there is a great difference in weight and color. Jo

Hi Jo,
I saw your comment through our customer service representative. If these are not marked, how do you know they are 15th or 16th century?
For faster service, please respond via a comment box.
Thanks,

Hi Jo,
Apologies that the comment box option doesn't seem to be working for you. I've been researching these through my extensive library of books on early metalwares and have not been able to find anything to point to these being 15/16th C or area of origin. The lack of marks is a bit concerning as production of any kind of glass, metal or ceramics was pretty heavily regulated by guilds etc.

My initial thought are even if these are old, they are so plain as to warrant a fairly modest value. Do you mind if I reach out to former colleagues of mine at some of the auction houses in NYC and London for their thoughts? I'd like their opinion but need your OK to reach outside of Mearto. There won't be an additional cost to you but it may take a bit longer to finish this appraisal. I apologize for the delay but want to do my due dilligence on this appraisal.
Please email our customer service as you've done previously and I'll reach out ASAP.
Thanks!

Hi Jo,
I've reached out again to the former colleague I'd initially asked about these - he was away for the Memorial Day holiday and I suspect the email got buried, and have also reached out to ANOTHER person for a second (or third) opinion.
I do have contacts at museums but they are usually not willing to authenticate from photos.
I'll be in touch as soon as I hear anything - I'm SO SORRY this is taking so much longer than I thought :(

Hi Jo,
My specialist friend also thought these were pewter; this was their comment:
"earlier pewter did contain lead in varying percentages. Based on the fact there are no marks and there does appear to be significant wear and damages, you’re probably looking at less than $50. If they are in fact lead, less than that."
I've taken the date line off of my initial appraisal and removed the date line as it's impossible to say how old these are but am leaving my initial value of $75-150 on these as I think they have decorative value, if for a limited market.
Thanks, Delia
