With this update, we hope it’s easier than ever to keep every item of your collection fully documented.

- Storage location (no more guessing where you stored that piece!)
- Pictures and PDFs (a handy way to keep invoices)
- Your own ID number for each item
- Private and public comments
- Quantity
- Adjectival grade
- Exchange status

Here’s everything you can log:
- Acquisition place, date, and price
- Third-party grading (service, grade, designation, CAC sticker, cert number — we’ll build the verification link!)
- Size, weight, axis (especially for ancient coins)

Many countries continue having bimetallic coins, so I guess it's worth it. I believe it's also a way to make counterfeits more difficult.
