2007-W Burnished Silver Eagle NGC MS70 ER

The 2007-W Burnished Silver Eagle NGC MS70 ER is a silver coin. The offering identifies 2007 as its issue year. The listed metal amount is 1 oz. The stated certification is NGC MS70.

History and background

The American Silver Eagle began in 1986 as a United States Mint bullion program. It brought a standardized one troy ounce silver coin to a modern market while drawing on an earlier period of American coin art. The series includes bullion, Proof and other collector formats, and its design history has continued across changing mintmarks, packaging and certification practices. A dated Silver Eagle belongs to that continuing program, rather than to the circulating silver dollar issues of the nineteenth century.

Design and product identity

Adolph A. Weinman’s Walking Liberty image supplies the obverse: Liberty strides forward with the flag, branches and a rising sun. The image originated on the half dollar introduced in 1916. The original reverse, by John Mercanti, uses a heraldic eagle and shield. A new reverse by Emily Damstra, showing an eagle approaching a landing with an oak branch, entered the series in 2021. The distinction between these reverses matters independently of a coin’s grade or Proof finish. Its stated issue date places it before the 2021 reverse redesign.

Understanding the metal content

Precious metal ounce weights use the troy system. One troy ounce equals 31.1034768 grams, while a kilogram equals one thousand grams. Fineness states the proportion of precious metal in an alloy; fine metal weight states the amount of that metal. An alloyed coin’s gross weight includes its other metals as well. These measurements explain why a denomination, a package weight and a stated fine metal amount should not be treated as the same specification.

Certification and the stated grade

NGC stands for Numismatic Guaranty Company. The service authenticates and grades submitted coins rather than manufacturing the original issue. This offering is identified as MS70. The numeric assessment concerns condition, not gold or silver purity. A certification number identifies a grading record, while the issue date identifies the coin. The holder label can also carry designations that are separate from both the coin’s denomination and its metal content. MS means Mint State and belongs to the uncirculated range of the traditional grading scale. An uncirculated coin can still have production or handling marks, so the number supplies a more specific assessment than the word uncirculated alone.

Details of this version

The Early Releases or related release designation concerns the grading service’s eligibility and submission timing. It is separate from the numeric grade and is not proof that this was one of the first coins struck from a particular die.

Preserving the product

Preserving the surface and the original identifying information helps retain the product’s physical history. Handle an unencapsulated collectible by its edges where appropriate and avoid polishing or abrasive cleaning. Keep a certified holder or stated assay package intact when retaining its identification matters. A brighter surface created by cleaning is not the same thing as a higher original condition grade.
