The offering identifies 2011 as its issue year. The listed metal amount is 1 oz. The stated certification is PCGS SP70.\u003c\/p\u003e\u003ch2\u003eHistory and background\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eDesign and product identity\u003c\/h2\u003e\u003cp\u003eAdolph 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.\u003c\/p\u003e\u003ch2\u003eProduct specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct format:\u003c\/strong\u003e Coins\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed metal amount:\u003c\/strong\u003e 1 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFineness or alloy:\u003c\/strong\u003e .999 fine silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMint or maker attribution:\u003c\/strong\u003e United States Mint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIssue-year selection:\u003c\/strong\u003e 2011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrading service:\u003c\/strong\u003e PCGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed grade:\u003c\/strong\u003e SP70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 7011PBSE\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eUnderstanding the metal content\u003c\/h2\u003e\u003cp\u003ePrecious 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.\u003c\/p\u003e\u003ch2\u003eCertification and the stated grade\u003c\/h2\u003e\u003cp\u003ePCGS stands for Professional Coin Grading Service. The service authenticates and grades submitted coins rather than manufacturing the original issue. This offering is identified as SP70. 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. SP identifies a Special or Specimen strike category in the service’s usage. It should not be relabeled as ordinary MS or Proof merely because the numeric score is the same.\u003c\/p\u003e\u003ch2\u003ePreserving the product\u003c\/h2\u003e\u003cp\u003ePreserving 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.\u003c\/p\u003e\u003ch2\u003eMaterial, design and numismatic identity\u003c\/h2\u003e\u003cp\u003eA product’s history is carried by several different kinds of information. The issuing or manufacturing name explains its origin, the design identifies its subject, the metal specification describes its material and the condition language describes its preservation. A date can connect the piece with a particular program or historical period without proving that it is rare. These features remain meaningful together even when two offerings contain similar amounts of precious metal. Keeping them distinct provides a more accurate description of the actual object.\u003c\/p\u003e\u003cp class=\"kz-product-sources\"\u003e\u003cstrong\u003eHistorical and technical references:\u003c\/strong\u003e \u003ca href=\"https:\/\/www.usmint.gov\/learn\/coins-and-medals\/collectible-coins\/american-eagle.html\"\u003eU.S. Mint background\u003c\/a\u003e, \u003ca href=\"https:\/\/www.ngccoin.com\/coin-grading\/grading-scale\/\"\u003eNGC grading reference\u003c\/a\u003e.\u003c\/p\u003e","brand":"Kzoo Bullion","offers":[{"title":"Default Title","offer_id":52514898936103,"sku":"7011PBSE","price":162.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/5046\/7367\/files\/media_76b93dc1-9794-4e4c-8a53-4300d128a766.jpg?v=1793693135","url":"https:\/\/kzoobullion.com\/products\/2011-w-burnished-silver-eagle-pcgs-sp70","provider":"Kzoo Bullion","version":"1.0","type":"link"}
