<p>[QUOTE=&quot;Dansco_Dude, post: 25380758, member: 147679&quot;]After playing around with my <a href="https://www.cointalk.com/threads/revisiting-numi-testing-the-latest-gpt-4-update.412086/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/revisiting-numi-testing-the-latest-gpt-4-update.412086/">AI coin grading project</a> for half a year, I&#039;ve started to sour on the idea. I think Technical Grading will eventually be accurate enough to be useful, but I don&#039;t think the market will accept it. PCGS, NGC, and CAC are just too dominant. People want and trust the judgment of these companies. I just can&#039;t see AI grading taking off in a big manner.</p><p><br /></p><p>But...after testing AI over a thousand times, I noticed that it&#039;s extremely accurate in identifying coins 99% of the time. Specifically identifying the series, year, and mintmark. [For US and World Coins, not medals or tokens. Nor varieties/errors]</p><p><br /></p><p>I&#039;ve been working towards a robotics system to identify and sort coins using ROS2, a Raspberry Pi, a mini camera for the AI to take and analyze images, and Legos bricks. Consider it Numi v2.</p><p><br /></p><p>The goal is to build a coin-sorting robot that uses AI to intelligently sort coins. Imagine a reverse Coinstar that spits back out valuable coins.</p><p><br /></p><p>My friends working at coin shops lament about all the bulk coins coming in that they don&#039;t have time to sort. Such as wheat cents and silver world coins. Which is a bummer because they&#039;re leaving a bunch of money on the table.</p><p><br /></p><p>I&#039;m starting with wheat cents, but the goal is to work towards sorting other US coins, silver world coins, and eventually identifying varieties &amp; errors.</p><p><br /></p><p>Attached are images of the initial designs I built using Lego Studio Designer. I&#039;ll be building the physical prototype over the next few weeks.</p><p><br /></p><p><img src="https://i.imgur.com/lr152dB.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><img src="https://i.imgur.com/exGQOUw.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>What would you want out of a coin-sorting machine? How could this machine help you or your shop?[/QUOTE]</p><p><br /></p>
