Collector guide

Get started with a collection, import photographs, and understand what the catalog is showing you.

Start with an empty collection

Open your collection and choose Import photos to work through a batch, or use Add specimen to enter a coin or banknote by hand. Counts on the overview reflect what you have actually saved.

Import and review a batch

Use the photo library or phone camera. Choose whether to allow AI analysis. Open a processed photo to check the suggested attribution, adjust the crop, and pair another photo as the reverse. Save only the specimens you have reviewed.

Read a valuation

Open a specimen and add realized sales from original lot pages. Record the currency and whether each price includes the buyer’s premium. If the app shows Insufficient market evidence, it has too few comparable sales for that estimate.

Find missing pieces and manage access

Themes show which checklist entries you own. Open a missing entry to search configured sources. Use Settings to export your records or delete your account. Manage agents and API keys under Developer.
