Amiga, sorry I didn't explain further....my grandmother was a very talented lady that won awards all over and was even hired by Disney to do bisque porcelain. My grandfather was a artisan as well and professionally made furniture and framed. So...their items were not "home crafts" as so many of us make.
The Staffordshire item is a round ceramic plaque that has been mounted for wall presentation. These were very popular in the early 90's (generally 1900 - 1940). They were sold as ceramic discs and many do have hanging insets on the back. However, many people wanted to make the plaque more pronounced in presentation and had them mounted, generally on velvet and then wood framed, generally in a golden/gilded frame. Cannot tell if yours is hand painted or decal ware. Irregardless, these are selling between $30 - $45.
As for the others, cannot say as they are Staffordshire. Many factories produced items of this sort during the same time period.
