Divide by purpose first
Separate permanent personal-collection cards, active selling inventory, unsorted intake, and low-priority bulk. Purpose changes more often than sport or set, so it is the most useful first layer.
- PC and display
- Active inventory
- Needs research
- Needs photos or data
- Bulk and long-term storage
Give every container an address
Use short labels such as BOX-A03 or SHELF-B2. Store that location on important card records. A perfect catalog is useless if it cannot lead you back to the physical card.
Catalog by value and activity
Start with cards that are valuable, listed, frequently shared, newly purchased, or emotionally important. Bulk cards can be summarized by lot until they need individual records.
Create an intake station
Every incoming card should pass through the same small workflow before storage: identify, photograph, record cost, assign status, and choose a location. This prevents the unsorted pile from rebuilding itself.
