Charger plate - At a dead end with touch marks (Maker Identified)

[Maineiac]

I have this old charger plate and am having a heck of a time making out the touchmarks. I am hoping someone might recognize throne on the right, but I'm not going to get my hopes up. I've gone through my entire book of marks and searched online without much luck. "LONDON" was used in both England and America which doesn't make it any easier. I'm going to keep researching, but any information would be very much appreciated. The second photo shows some rough annotations. I pulled this from a scrap metal bin at the local dump. Perhaps it was there for a reason?

Definitely pewter that has seen better days.

This is a pretty good site, Pewterbank...spend some time on it and see if it can help you!

Quality marks (crowned rose or crowned X) were used to denote the quality of pewter. (These marks stopped in the 18th century - unless they were copied)

Hi, I agree, it certainly has seen better days. What it actually says is tough to make out. The mark on the right appears to say something like "SOBERT"...... There are two stamps that say "LONDON". I have a book full of markings but can't find any reference to "SOBERT". If that is indeed what it says, I'm wondering if it might be a family name.

I'm going to attach a few more (better quality) photos. Based on the previous replies, do you think it would be a safe bet to consider this plate 17th or 18th century?

It looks like an 18th or very early 19th century plate like I have seen and had. They were utilitarian and not treated with much respect as they got old. Because they are so soft they damaged really easily. The info provided should help you identify it.

I got some help on this one from a gentleman in Canada and thought I would follow up. It turns out that the plate was made by a Robert Jupe who died in 1737. Thanks for the great leads.
