The image appears to show the "Annie and Grace" collector's plate from the 1983 Annie collection, painted by artist William T. Chambers and produced by Edwin M. Knowles China Company. 

Plate Details

• Manufacturer: Issued by Edwin M. Knowles China Company as part of the limited-edition series distributed via the Bradford Exchange. 

• Year: 1983

Based on the back of your plate, you have an authentic, specific individual pressing from this limited run. Here is the exact breakdown of what the markings mean, along with its current market value:

Reading Your Plate Markings

• Plate Number E8710: This is the unique sequential production number assigned strictly to your individual plate during its manufacturing run.

• The "Third Issue": This tells us where the plate falls chronologically in the collection. It confirms this design was the third unique scene released in the broader Annie Collector's Plate Series.

• Bradex Number 84-K41-5.3: This is the official cataloguing number used by the Bradford Exchange (the primary exchange database for limited-edition plates). The code acts like an item barcode for collectors: 84 indicates the origin country/catalog, K41 identifies the Knowles series, and 5.3 denotes the specific plate within the series. 

• 100 Firing Days: This confirms the manufacturing scarcity. Once the 100-day production window closed in 1983, the molds were permanently broken. 

Current Market Value

In the current collectibles market, individual plates from this specific 1983 Knowles collection generally retail between $10.00 and $25.00 USD. 

To fetch the higher end of that range, a collector would typically look for the plate to be in pristine condition, accompanied by its original cardboard box, and the paper Certificate of Authenticity (COA).
