<p>[QUOTE=&quot;NSP, post: 3905711, member: 74849&quot;]I don’t know if you’ve already investigated it, but PCGS’s CoinFacts does have some of their TrueViews uploaded for all of the dates and mintmarks. Scarcer dates like 1909-S VBD and 1914-D have a pretty good spread of grades (even lower grades). All of the images are of good quality, so they should be good training images for a neural network. </p><p><br /></p><p>CoinFacts used to have all TrueViews uploaded, but unfortunately unscrupulous crack-out artist dealers (i.e.- dealers who crack out and resubmit coins for higher grades) were offended that CoinFacts listed all TrueViews for a coin (including TrueViews that were taken when the coin was graded lower). Having lower graded TrueViews available for viewing on CoinFacts interfered with their business practices, so they complained to PCGS and lobbied them to removed ALL TrueViews from CoinFacts. Fortunately PCGS eventually came up with a compromise where they uploaded TrueViews for coins that were listed in registry sets. While not a perfect solution, this nerfed version of CoinFacts is all the better it’s going to get.[/QUOTE]</p><p><br /></p>
