The Seated Liberty dime was designed by Christian Gobrechtl and was minted from 1837 until 1891. The obverse design was on every United States coin during this period. Gobrecht got the job of designing the dime after Chief Engraver William Kneass suffered a stroke. The coin contained 90 percent silver and ten percent copper. The size of the coin was set at .705 inches in diameter. This size and composition of the metal would continue until 1965.
