These attractive small (6-12") plates are in a very dark blue and printed in the pattern known as "Curly Pagodas" or "House Boat". The border pattern is called "Trellis Diaper".
Michael Messenger discusses and illustrates the pattern on page 65 of his "Coalport" book. He credits the first use of the pattern to Thomas Turner of the Caughley Works.
Both plates are in excellent condition. There are no chips, no cracks, no crazing and no repairs. Each plate rings when tapped.
These plates are unmarked. However, other pieces of this partial set bear Coalport's distinctive impressed numeral "2". That mark was used c 1815-25.
I have 8 of these pretty plates available. They are being offered and priced in sets of two.
