Overview
Identification is highly confident based on the clear, unambiguous factory mark. The circular 'Royal Winton Grimwades Made in England' mark featuring a large stylized 'R' was introduced circa 1934 and used through the 1950s. The pattern name 'ROSA' is explicitly stamped.
Story
Royal Winton is a brand of Grimwades Limited, a Staffordshire pottery established in 1885. They became world-renowned in the 1920s and 1930s for their densely patterned 'Chintz' designs. The 'Rosa' pattern, produced during their mid-century peak, reflects the enduring popularity of English floral transferware. The market for mid-century English earthenware, particularly floral and chintz-adjacent patterns, is softer today than in the early 2000s. Buyers are highly selective, often preferring pristine condition.
Maker / Origin
Royal Winton (Grimwades)
Condition & Value
The seller explicitly notes crazing, which is a common network of fine cracks in the glaze typical of vintage English earthenware. While expected for the era, heavy crazing or associated staining will lower the value.

Sold comps, value drivers, and venue guidance pulled from recent auction results.
The market for mid-century English earthenware, particularly floral and chintz-adjacent patterns, is softer today than in the early 2000s. Buyers are highly selective, often preferring pristine condition. Large sets are frequently difficult to sell online due to high shipping costs relative to the item's value, meaning local sales or breaking sets into smaller, shippable lots often yields better results.
▲ Substantial set size (24 pieces) offers an instant partial dinner service.
▲ Clear Royal Winton factory mark confirms mid-century Staffordshire origins.
▼ Unverified plate dimensions — exact sizes are needed to confirm if these are dinner, salad, or dessert plates.
▼ Unverified edge condition — hidden chips or hairlines would significantly reduce the set's value.
▼ Severity of crazing is unknown — heavy crazing with discoloration trades at a steep discount to clean glaze.
Best Venue
Given the high shipping costs for 24 plates, consider listing locally on platforms like Facebook Marketplace to maximize net profit. If selling online, ensure the plates are double-boxed and explicitly photograph the extent of the crazing. Alternatively, splitting the set into three lots by size may attract buyers looking for specific replacement pieces.
Upside Potential
If the plates are confirmed to be free of chips, cracks, and glaze staining (clean crazing only), and the largest plates are full-sized dinner plates (10 inches or larger), the set could reach the higher end of the range to a dedicated collector of the Rosa pattern.
