Common antique pewter trademarks include an eagle with its wings spread or poised for flight or a straight band of four square touches that resembles an English hallmark. Another common antique pewter trademark is a state's coat of arms modified to include the author's initials.
Antique pewter trademarks, also called touch marks, come in a variety of sizes, shapes and designs and commonly include either the name of the pewterer or his initials. Other common antique pewter trademarks include crowns, such as Frederick Bassett's New York City trademark with a rose and crown design.
Antique pewter trademarks show English influence if dated before the American Revolution such as the "Lion in Gateway" trademark by Nathaniel Austin. After the Revolutionary War, pewterers began to use symbols of freedom and American independence in their works, such as the eagle. Nathaniel Austin's later works following the revolution demonstrate this, such as his "Eagle" trademark. Other pewter trademarks that involve eagles include Thomas Boardman's Connecticut trademark depicting an eagle and a shield as well as Samuel Kilborn's Maryland trademark that shows an eagle poised on a branch ready for flight.
Antique pewter trademarks sometimes display dates. If the date is given on an antique pewter piece, it signifies the date the creator started business rather than the date the creator finished that specific piece.
