Coin Slab
Coin slab is a type of holder for a coin. Slabbed coins are typically from one of the coin grading companies. The practice of sending coins to third-party grading companies and then "slabbing" them began in 1986. When a grading company grades the coin it is sealed in a tamper proof slab with a barcode and a hologram. To prevent counterfeiting, holograms were attached to the graded coin slabs beginning in 1989. The early coin slabs did not have a hologram. History Slabbing coins is a practice which began in 1986. It was a way to remove coin grading controversies by having a third party certify the coin's condition. There are major coin certification companies that encapsulate coins in an acrylic case after grading the coin. Companies like ANACS, Numismatic Guaranty Company (NGC), Professional Coin Grading Service (PCGS), International Coin Certification Service and CAC accept coins which they grade, certify and then slab. Collectors rely on these third party grading companies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coin Grading
Coin grading is the process of determining the grade or condition of a coin, one of the key factors in determining its value. A coin's grade is generally determined by six criteria: strike, preservation, luster, color, attractiveness, and occasionally the country/state in which they’re minted. Several grading systems have been developed. Certification services professionally grade coins for tiered fees. Overview A "grade" measures a coin's appearance. There are generally five main components which determine a coin's grade: strike, surface preservation, luster, coloration and eye appeal. Grading is subjective and even experts can disagree about the grade of a given coin. History U.S. coin grading has evolved over the years to a system of finer and finer grade distinctions. Originally, there were only two grades, new and used. This changed to the letter grading system beginning with the lowest grade – ''Basal State'' (also ''Poor'' (PO)), then continuing ''Fair'' (Fr), ''Abou ...

ANACS (coin Grading Company)
The American Numismatic Association Certification Service, better known as ANACS, is a coin grading company founded in 1972. History Originally founded in June 1972 as the American Numismatic Association's authentication service, ANACS expanded into third-party coin grading in March 1979. ANACS was founded in response to the rise in counterfeit and altered coins in the numismatic marketplace. During the coin collecting boom of the 1960s, counterfeiters would alter common-date coins, and either add or remove a mintmark in order to sell the coins as their more-valuable counterparts. (For example, an 'S' mint mark would be added to a 1909 VDB Lincoln cent in order to increase the coin's value by making collectors think it was a genuine 1909-S VDB cent). ANA sold ANACS to the publisher of ''Coin World ''Coin World'' is an American numismatic magazine, with weekly and monthly issues.

Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other Holography#Applications, applications. In principle, it is possible to make a hologram for any type of Holography#Non-optical holography, wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be Computer-generated holography, computer-generated by modelling the two wavefronts and adding them together digitally.
