<p>[QUOTE=&quot;karrlot, post: 91834, member: 4476&quot;]I don&#039;t understand why you would do that</p><p><br /></p><p>B]Size and Dimension[/B] - I already know or can find this out.</p><p><br /></p><p><b>Weight</b>- same goes here.</p><p><br /></p><p><b>Color</b> - color charts could be prepared, with dozens of subtle variations for color standardization.&nbsp; Coloration may indicate where the coin spent most of its existence.&nbsp; </p><p><br /></p><p>Isn&#039;t it true that if you had multiple variations of a color, two people might disagree on the exact match?</p><p><br /></p><p><b>Structure </b> - bends, dents, strike features, etc.&nbsp; Measure and note.</p><p>Yup, you could do this.&nbsp; </p><p><br /></p><p><b>Texture</b>- fine-grained textures, pock marks, dings, polish marks, etc.&nbsp; This is a big one for coin people.&nbsp; You probably should measure and standardize coin-relief features; coin edges, bass reliefs, letters, etc.&nbsp; At least discuss these features in empirical terms.&nbsp; Quantify.</p><p><br /></p><p><br /></p><p>I think this is already done.&nbsp; When you&#039;re describing a coin, you should list any major defects in it.&nbsp; You could measure the exact length and width of a scratch or ding, to the 1/100th of an inch, but most people don&#039;t have the ability to do that.&nbsp; &nbsp; </p><p><br /></p><p><b>Chemical Composition</b> - This could, and probably is, being used to identify fake coins and report metallurgical contents of modern coins.&nbsp; Metal alloys, especially ancient alloys, are a combination of several metals.&nbsp; The afghans talk about their seven-metal jewelry.&nbsp; The alloys have several metals becasue the ancient metallurgists had great difficulty removing unwanted elements like zinc.&nbsp; I suspect that old coins probably have chemical &quot;signatures&quot;, even by coin batchs and dates.&nbsp; I would not be surprised if some modern coins have elemental &quot;tracers&quot;.</p><p><br /></p><p>You&#039;re right - there probably are trace elements and metals in the coins, but no one seems to care about the trace elements, they just care what the purity of gold or silver is.&nbsp; 90%, 80%, or 40% seem to cut it.&nbsp; It really wouldn&#039;t matter to me if it was 40.019732% silver. </p><p><br /></p><p><b>Weathering and Alteration</b> - Most circulated coins have tinges of silver, and or, basemetal alteration products.&nbsp; The different colors and texutures indicate the presence of different metal oxides, chlorides, carbonates, and other metallic salts.</p><p><br /></p><p><br /></p><p>I&#039;m not knocking your ideas, I guess my point is that you could do all of this, but most of it wouldn&#039;t matter.&nbsp; If it was important to coin collectors, they would have done it by now.&nbsp;&nbsp; </p><p><br /></p><p>What kind of a scale would you use to measure eye appeal?&nbsp; Whos eye would you use?</p><p><br /></p><p>I didn&#039;t know what you meant by &quot;emperical terms&quot; so I looked it up.&nbsp; One of the definitions was &quot;capable of being verified or disproved by observation or experiment &quot; but ironically the other one was&nbsp; &quot;relying on experience or observation alone often without due regard for system and theory&quot;.</p><p><br /></p><p><br /></p><p>Likewise, you could develop all of those same types of things to evaluate a car.&nbsp; But when it was time to buy a new car, would you care about trace elements in the engine block?&nbsp; Would you care what size, to the exact demensions, are the dings from the hail damage, or would a general statement of &quot;very light hail damage&quot; suffice?&nbsp; You could give the PMS numbers of the paint, but &#039;banana yellow&#039; is more descriptive to most people who buy or drive a car than PMS 214 (or whatever descriptor they use for colors).&nbsp; </p><p><br /></p><p>You&#039;d still want to see the damage before you bought it.&nbsp; The determining factor would be does the engine run well, how ugly does the damage make the car look?&nbsp; Do you like the color?[/QUOTE]</p><p><br /></p>
