The offering identifies 2011 as its issue year. The listed metal amount is 1\/10 oz. The stated certification is NGC Proof 70.\u003c\/p\u003e\u003ch2\u003eHistory and background\u003c\/h2\u003e\u003cp\u003eThe modern American Gold Eagle program started in 1986. It adapted the visual legacy of Augustus Saint-Gaudens to a bullion coin intended to carry a specified amount of fine gold. The program’s one ounce, half ounce, quarter ounce and tenth ounce sizes belong to the same family, but they are separate denominations and physical formats. These coins are modern issues, distinct from the ten dollar gold eagles that circulated before 1933.\u003c\/p\u003e\u003ch2\u003eDesign and product identity\u003c\/h2\u003e\u003cp\u003eThe obverse follows Saint-Gaudens’ standing Liberty, with a torch and olive branch, originally associated with the twenty dollar double eagle. Miley Busiek’s original reverse depicts a family of eagles. A newly designed eagle portrait replaced that reverse during 2021. The design transition is separate from the difference between bullion and Proof production, so both date and any Type designation help identify a particular offering. 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 Gold\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\/10 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFineness or alloy:\u003c\/strong\u003e 22-karat gold alloy\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 NGC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed grade:\u003c\/strong\u003e Proof 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 11NPGE$5\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\u003eNGC stands for Numismatic Guaranty Company. The service authenticates and grades submitted coins rather than manufacturing the original issue. This offering is identified as Proof 70. 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. A Proof grade belongs to a specially manufactured coin. NGC generally uses PF and PCGS generally uses PR, so service terminology should be read in its own context rather than silently converting a Proof into a Mint State issue.\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":52515601416487,"sku":"11NPGE$5","price":642.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/5046\/7367\/files\/media_0f7a3978-afd6-47b6-be47-2977a10d0473.jpg?v=1793696154","url":"https:\/\/kzoobullion.com\/products\/2011-w-1-10-oz-proof-gold-eagle-5-ngc-pf70","provider":"Kzoo Bullion","version":"1.0","type":"link"}
