<p>[QUOTE=&quot;TypeCoin971793, post: 2443006, member: 78244&quot;]On a whim, I tried a little experiment. I went on eBay to the IHC category and typed in all of the dates from 1864 to 1879 and some others. Below are the number of results, but they can be reduced by 10% or so to allow for counterfeits, non-applicable listings, etc.</p><p><br /></p><p>1864: 1704</p><p>1865: 850</p><p>1866: 690</p><p>1867: 710</p><p>1868: 562</p><p>1869: 482</p><p>1870: 373</p><p>1871: 262</p><p>1872: 412</p><p>1873: 434</p><p>1874: 683</p><p>1875: 678</p><p>1876: 397</p><p>1877: 288</p><p>1878: 263</p><p>1879: 583</p><p><br /></p><p>1908 S: 660</p><p>1909 S: 363</p><p><br /></p><p>Interesting distribution. Are the keys and semi-keys as rare and hard to find as their prices suggest? 1878&#039;s actually are harder to find than any of the above dates except 1871. This algoritm might be flawed if one is trying to get at exact rarity, but I believe it can show relative rarity. Comments? Other algorithms?[/QUOTE]</p><p><br /></p>
