<p>[QUOTE=&quot;Dansco_Dude, post: 24821280, member: 147679&quot;]Calling on all opinionated coin graders, your help is requested!</p><p><br /></p><p>Following up on my previous <a href="https://www.cointalk.com/threads/i-created-an-ai-to-objectively-grade-coins-give-it-a-try.408631" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/i-created-an-ai-to-objectively-grade-coins-give-it-a-try.408631">post</a>, it has been a blast building out my AI coin grading and identification app these past two weeks. Folks here have given a lot of great feedback and I&#039;ve made numerous <a href="https://www.cointalk.com/threads/i-created-an-ai-to-objectively-grade-coins-give-it-a-try.408631/page-2#post-24821276" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/i-created-an-ai-to-objectively-grade-coins-give-it-a-try.408631/page-2#post-24821276">updates</a> to Numi since. Here is a <a href="https://i.imgur.com/vy93SMh.mp4" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://i.imgur.com/vy93SMh.mp4" rel="nofollow">live video demo</a> showing the latest update with PCGS API integration.</p><p><br /></p><p>A key part of Numi&#039;s logic is that it references detailed grading criteria I&#039;ve compiled based on the top TPG&#039;s public grading standards. Whenever Numi is asked to grade a coin, it references these grading standards to give a final estimated grade.</p><p><br /></p><p>I&#039;ve been running around to various coin shops to talk with dealers to get their feedback on the wording of Numi&#039;s grading criteria, but I&#039;m getting a lot of mixed messages. One coin shop dealer said,</p><p><br /></p><p><br /></p><p><br /></p><p>However the next day another dealer told me,</p><p><br /></p><p><br /></p><p><br /></p><p>So now I&#039;m turning to the wisdom of the crowds. I&#039;m looking for opinionated coin graders to share their thoughts on Numi&#039;s grading criteria.</p><p><br /></p><p>Below is what Numi currently uses:</p><p><br /></p><p><br /></p><p><br /></p><p>I would love to start a discussion and see what you believe should be changed. I have also created a <a href="https://forums.collectors.com/home/leaving?allowTrusted=1&amp;target=https%3A%2F%2Fdocs.google.com%2Fdocument%2Fd%2F1M8R0x-2KF9MMkfb_tG284BUqC_AVBr3byilJ9LQEGg8%2Fedit%3Fusp%3Dsharing" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://forums.collectors.com/home/leaving?allowTrusted=1&amp;target=https%3A%2F%2Fdocs.google.com%2Fdocument%2Fd%2F1M8R0x-2KF9MMkfb_tG284BUqC_AVBr3byilJ9LQEGg8%2Fedit%3Fusp%3Dsharing" rel="nofollow">public Google doc</a> with these criteria for easier sharing and commenting. I&#039;ll update Numi&#039;s logic based on the discussion here, continue to test the app with graded slabs, and post the results here.</p><p><br /></p><p>This continues to be a wonderful community. Thank you all for the feedback you&#039;ve shared so far. Let&#039;s see if we can make coin collecting more approachable.</p><p><br /></p><p>If you want to play around with Numi directly, you can check it out <a href="https://www.asknumi.com/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.asknumi.com/" rel="nofollow">here</a>.</p><p><br /></p><p>- Dansco Dude[/QUOTE]</p><p><br /></p>
