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.
