<p>[QUOTE=&quot;Cringely, post: 873983, member: 22271&quot;]I&#039;m about 90% done with the article relating grade and market pricing. But then you are aware of the old dictum: the first 90% of the job takes 90% of the time/money/manpower. The final 10% takes another 90% of the time/money/manpower:headbang:.</p><p><br /></p><p>I expect to finish the article in the next month or so and submit it to the <i>Numismatist</i>.&nbsp; My fear is that it will be too scholarly as it is based on a lot of statistical analysis of pricing over the last 30 years.</p><p><br /></p><p>I took the price for all 95 separate copper and silver type coins listed in the Red Book and summed up their listed values for each grade. This 95-coin set can be thought of as a portfolio or an index fund. Because of their relatively high prices, I did not include the 1793 Chain Cent, the 1796 quarter and the 1796-97 Bust Half dollar. These three account for 60-75% of the total valuation of all US coins in lower (G and VG) grades. Even in the higher grades (e.g., MS-60), they account for half the total valuation. I also did not include any clad (post-1964) coins.</p><p><br /></p><p>I will give two of the observations regarding the price of type coinage:secret::</p><p>1) the cost, as you jump up in grade, is a relatively constant percentage.</p><p>2) An argument can be made for considering MS-64 as a separate (full) grade.[/QUOTE]</p><p><br /></p>
