US 1983 DIME NO S PROOF 70 ULTRA CAM
-
Struck at the San Francisco Mint without the iconic “S” mint mark, the **1983 No S Proof Roosevelt Dime** stands as one of the most famous and sought-after modern rarities in United States numismatics. Discovered in standard 1983 proof sets, this error occurred when mint officials mistakenly used an un-punched obverse die to produce proof coinage, resulting in an estimated mintage of only 3,000 to 3,500 pieces surviving before the error was caught and corrected.
-
Achieving the pinnacle grade of **Proof 70 (PF70 / PR70)**, this coin represents absolute perfection. Free from any microscopic hairlines, contact marks, or mint imperfections under 5x magnification, its state of preservation is flawless. The **Ultra Cameo (NGC)** or **Deep Cameo (PCGS)** designation highlights the striking, dramatic contrast that defines elite proof strikes: intensely frosted high-relief details—including President Franklin D. Roosevelt’s portrait on the obverse and the torch, olive branch, and oak branch on the reverse—stand out against deeply mirrored, water-clear fields.
-
Beyond its technical perfection, the coin’s significance lies in its place within major Registry Sets. While standard 1983-P business strike dimes were produced by the millions in Philadelphia without a mint mark, they lack the brilliant mirror finish, raised rim, and sharp frosted relief of this genuine proof error.
-
For collector portfolios and elite numismatic displays, a perfect 70-graded 1983 No S Dime represents the ultimate intersection of modern rarity, mint error history, and condition census leadership.
