I finally have an update to share with readers on the next iteration of Numi.

After playing around with AI coin grading for half a year, I've started to sour on the idea. I think Technical Grading will eventually be accurate enough to be useful, but I don'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't see AI grading taking off in a big manner.

But...after testing AI's computer vision capabilities over a thousand times, I noticed that it'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]

I've transitioned Numi to be a coin-sorting robot that uses AI to intelligently identify and sort coins. Imagine a reverse Coinstar that spits back out valuable coins.

After a lot of tinkering and coding, I built the initial alpha prototype and flow for Numi v2.0. The prototype can capture images on both sides of a coin, send an API request to GPT-4o for analysis, and display results identifying the coin's type, country of origin, and year.

Tech Specs

Below are some of the problems encountered, lessons learned, and what I plan for the next iteration.

Plans fir the next Iteration

Based on lessons learned, I've already designed what the second iteration should look like. The Lego parts are being mailed and I aim to build the next iteration in a few weeks.

My goal at the moment isn't to sell Numi or convince others that it's valuable. But rather use it as a tool to understand the needs of collectors and dealers and see if AI can make numismatics more approachable.

If any readers have thoughts or feedback they would like to share, they can always email me via DanscoDude@gmail.com or follow my progress on my Instagram @Dansco_Dude

Will keep you updated!!
