Bilston & Battersea collectible enamel boxes fall under the category of "smalls" you might see at an estate sale. They are small trinket or pill boxes usually with a hinged lid. Also called Battersea enamels, these little boxes are made with enamel on copper, and were originally made in the Battersea district of London from about 1750 to 1756.
The boxes often have a holiday theme such as Christmas, Valentine's Day, Mother's Day, or Happy Birthday. The scenes are often similar to Norman Rockwell designs. Commemorative editions were also made, including Prince Charles' 60th birthday, Ronald Reagan, and the American Bicentennial. One particular line, Halcyon Days, was sold at Tiffany's for a period of time, so having the box and inserts will make the item more valuable.
Prices can reach into the hundreds for Bilston and Battersea trinket boxes, depending on age and design. Bilston and Battersea discontinued production of their enamel line in 2010, so the beautiful little boxes will only increase in value since more will never be made.
