Storing a 100+ Slab Collection: When You Outgrow Single Cases

The first hundred slabs fit in two cases. The next hundred requires a system.

The Inflection Point

At about multiple slabs, single travel cases stop being viable for your main collection. You need a tiered storage system: a working tier (recently acquired, frequently handled), a vault tier (long-term holds), and a display tier (rotation).

Working Tier

Foam-fitted hard cases sized to your dominant grader. Two to four cases live on a shelf at desk level. Add new acquisitions here and rotate to vault tier monthly.

Vault Tier

High-capacity slab drawers or stackable storage cases. Numbered slots cross-referenced to a spreadsheet:

| Slot | Cert # | Card | Grade | Value | Date Added |

Update the spreadsheet every time a card moves. The five minutes a week of bookkeeping saves hours during insurance updates.

Display Tier

Three to five cards in rotation, in UV-filtering display cases. Rotate quarterly back to vault.

Inventory Tools

Spreadsheet (Google Sheets, Airtable) for under 500 cards. Dedicated apps (Slab Sticker, CollX) for 500+ cards.
