Thank you for submitting your item for appraisal. This appears to be a sterling silver liquor cup, manufactured in Birmingham in 1904, with the Birmingham silver hallmarks and the manufacturer or sponsor´s mark TW.
Most interesting is the enamel White Star Line flag and the engraved "SS Arabic" above it. The White Star Line won eternal fame for one of the ships they lost, the Titanic. Another ship with a tragic history was the steamship Arabic, she was torpedoed and sunk by U-24 on 19 August 1915 and had thus a similar fate as the Lusitania. This is a small but great piece of ocean liner memorabilia. Similar items sell in the price range listed, someone who had surviving ancestors on this ship might be willing to pay even more.
