Plans for the next iteration

• Mechanism to sort coins based on certain parameters
• Goal of reducing run time to 25 seconds per coin

Long Term Goals

• System to pull coins out of a pile and place them onto the machine
• Capture and store images in a database
• System to place coins into 2x2's and staple it shut
• System to print key info on 2x2's such as coin type, year, mint mark, silver content, etc
• Explore open-source AI models to reduce costs

Based on lessons learned, I've already designed what the second design iteration should look like. I've compartmentalized the coins and cameras from the sorting system. This way taking photos and analyzing coins will not be a bottleneck for sorting the coins. The Lego parts are being mailed and I aim to build the next iteration in a few weeks.

I'll be at the Summer FUN show this Thursday - Saturday. I'm hoping to chat with a lot of dealers & collectors to better understand how they currently tackle identifying and sorting bulk coins. The goal now isn't to sell Numi or convince others that it's valuable. But rather to understand the needs of collectors and dealers and see how AI can make their lives easier.

If you'd like to share your thoughts at the show, let me know which table you are at and I'll drop by! Even better if you have some Dansco albums for sale

What ideas do you have on the cameras?

The choice of using the GPT-4o model was because I used GPT-4 to power Numi v1.0 when the focus was AI grading. It proved excellent at identifying coins, so I knew it was a save bet.

I'm planning on testing open-source LLMs like llama 3 and others and use a gpu cloud provider to handle analysis. They should lower costs, but accuracy remains a question.

Shouldn't be too hard to update the code to call a different API
