My Collector Portfolio

Track exact diecast collector records, quantities, purchase details, condition, storage, documented market values, and gain or loss without filling missing evidence with invented prices.

Evidence-first portfolio reporting

Documented value appears only when verified exact-release completed sales are available. Records without qualifying evidence remain useful for identification and collection tracking while market fields stay pending.

Portable records

Export JSON or CSV backups before changing devices or clearing browser data. The completed portfolio interface can also support encrypted recovery-key backup and cross-device restore.
