Pewter experts...might have some really old plated

Very rough cast looking plates. I would assume German. Crown over rectangle with dash in it. Crown has some symbol in it too.

That mark doesn’t appear in my archive of the old “Pewter Tankards and Flagons” site.

Plates, not plated?

Do the other "physical" characteristics match pewter?

If it's a food service item, has heft and can be bent easily it is a safe bet.

I took his question as asking if these were antiques of value as opposed to puddle candidates.

But I’ve been wrong before...

The letters in the crown is the makers initials. The letter underneath is the date code. "O" under the crown is about 1864. For collecting value, a clear touchmark is a must.

The crown denoted English made pewter which was highly regarded because of the high quality standards of the guild. Continental Europe recognized that and would "imitate" English touchmarks to sell their product for a higher price. They'd even polish it and mark it like hallmarked silver. You may be able to see more clearly with better light and magnification what you actually have.

I don't own this book but it's about the best for for data in a single volume:

Cotterell’s Old Pewter: It’s Makers and Marks

I hope you've found an heirloom. And, I've never seen rough cast german pewter. They always seem to go overboard with design and execution and wouldn't think of anything they made being thought of as English.

Thanks guys
