About NumiAgent

Why I’m building NumiAgent

A coin can fit in the palm of your hand. The work of figuring out what it is can take up a tray, a spreadsheet, and half a browser window. I wanted one place to keep the photographs, the attribution I settled on, and the sources I’d want to check again later.

I want NumiAgent to help with the jobs that put collecting on hold. There’s the camera roll you still need to sort, the coin you haven’t identified, the price you can’t trace to a sale, and the set you keep checking to remember what’s missing. Those are the problems I keep coming back to as I build it.

Leave room to be unsure

The interesting part of identification is often the doubt. A worn legend can change the reading. A banknote may look familiar until you turn it over and notice a different signature. NumiAgent offers suggestions for you to review, with space to correct the crop, pair the two sides, and record your own attribution.

I take the same approach to prices. When you record a comparable sale, the date, grade, price basis, and original lot link stay with it. If the evidence is too thin for a range, I want the catalog to say so plainly.

Keep it yours

A collection can have personal notes, purchase details, or photographs you only want to keep for yourself. I’ve built the catalog to be private. You decide which photo batches to send for AI analysis and which tools can read your records. You can export your catalog and revoke access from your account.

Collectors should also be able to check the sources behind the software. Aurearia informed some of the collecting workflows. Public Nomisma records give selected rulers, mints, denominations, and materials a link back to a numismatic reference.

Tell me what your catalog is missing

If you use NumiAgent and hit a point where you reach for your spreadsheet or notebook, I’d like to hear what you were trying to record. The same goes for an attribution that was hard to correct or a checklist that didn’t match the way you collect.
