The listing is for an antique English cup and saucer in the "Dollar Pattern," dating back to the Georgian era, around 1810.
This pattern was popular among various English porcelain factories during the early 19th century, specifically around 1805-1810.
The set is often unmarked, with identification sometimes reliant on features like a green tally mark inside the cup's foot rim.
The "Dollar Pattern" can be found on pieces from various manufacturers, including Coalport.
The design typically features vibrant, colorful chinoiserie elements, as seen in the example of a similar "Flying Bird" pattern by Davenport.
Little hairline by the top of the cup visible inside. See pics.
