Product Details

Own a piece of British maritime history! This authentic white ceramic cup features the iconic red-and-white house flag and bold "CLAN LINE" typography. These vessels were the workhorses of the British Merchant Navy for over a century—perfect for any collector of nautical memorabilia or steamship history. The word "England" was added to British pottery marks starting in 1891 to comply with the U.S. McKinley Tariff Act. Antique (1891–1926): If it just says "England," it was likely made between 1891 and the early 1920s. This would make your mug officially antique (100+ years old). Vintage (Post-1926): If the mark says "Made in England," it generally points to a date after 1921–1926. Maritime Premium: Because this piece is branded for the Clan Line Steamers, it cross-collects into nautical memorabilia. Rare shipping line china in pristine condition can command higher prices, sometimes reaching $100+ at specialty auctions or high-end retailers like 1stDibs. The "Perfect Condition" Bonus: Collectors of antique ironstone prioritize pieces that have avoided "browning" or heavy crazing. A crisp, white background with sharp logo colors makes this piece a "top-shelf" example. Rarity of the Mark: The specific Ashworth mark on the bottom helps verify its age (c. 1891–1920), which is essential for achieving the full antique valuation. An antique Ashworth Bros. Ironstone Clan Line mug in perfect condition is generally valued between $55 and $125.
