How to catalog your collection properly (coins, cards, sneakers and more)

A collection without a catalog is just a pile of stuff. Here's what to record for every item — and why it matters for value, insurance and selling.

You know roughly what you own. But "roughly" doesn't help when you want to insure a collection, prove its value, or sell a piece without under-pricing it. A proper catalog is the difference between a collection and an asset.

What to record for every item

1. What it is — name, category, and a photo. Multiple photos for condition-sensitive items (cards, watches).
2. Condition — the single biggest factor in value. Use a consistent scale so your own gradings stay comparable.
3. What you paid and when — purchase price and date. This is the baseline every valuation starts from.
4. Current value — your best estimate, updated when you learn something.
5. Location — which box, binder or shelf.
6. The sale record — when you sell, log buyer, date and price. That's your history.

Why it pays off

• Insurance — insurers want documentation: a list with photos and values.
• Selling — a catalogued item with condition and history sells faster and for more.
• Knowing your numbers — total value, total invested, and profit or loss per item.

Start simple. Catalog your 20 most valuable items first, with a photo each. Once the habit is there, the rest follows.
