Διηνεκη, διαβασε αυτο που αφορα τον τροπο βαθμολογησης βασει τη σκαλα του Newcomb (ζευγη σπανιων και ειδικων μητρων).


The Newcomb varieties scale is a numismatic classification system created by Howard R. Newcomb to catalog die varieties of United States large cents minted from 1816 through 1857 (covering Coronet Head and Braided Hair types). Numbering (N-1, N-2, etc.) starts fresh for each calendar year. [1, 2, 3, 4]

Overview of the System

• [b]Scope[/b]: Middle and late date large cents (1816–1857). Early dates (1793–1814) use the Sheldon scale instead.
  
  
• [b]Designation[/b]: Denoted by an "N" prefix followed by a number (e.g., N-1, N-9) representing the specific obverse and reverse die pairing used during production.
  
  
• [b]Application[/b]: Major grading services like NGC Coin Grading and PCGS attribute these numbers to identify rare or specific die states
