How can I tell if a teacup is antique?

There are a few things to check when determining if you’ve got an antique teacup. First, check the bottom of the piece. If there are handwritten marks, the tea cup was made before the 1800s. If the teacup has a stamped logo or has letters or numbers that aren’t blue, it was made after 1850. A tea cup with a trademark was made after 1862. You can also shop a collection of antique teacups from some of the world’s top sellers on 1stDibs.
