England 1809 British Passage of the Duro - and similar items

Offered here is a pair of small wall plaques. They look as if they are made of plaster of some sort, based on sound and backing with hanger. Unsure what the coin looking part is actually made of, Sounds slightly denser, But is actually thinker there as well. Not sure if it is a replica or plaster, However based on the photos it looks like it is chalk.Definition of the coin area is decent, but not clearly defined. Look like they were painted over with gold paint with a darker wash on top rubbed off. I am unsure of exact age or maker of these plaques, but look prestigious. If you have any idea what era or really what they are, please let me know. Thanks in advance, appreciate your time. They measure 3 1/8" round. I take pride in my pictures, and are a valuable extension of my description. Please take time to see the product fully. Buy with confidence! Check out my other auctions by clicking here!
