Step 1
Choose a physical batch
Catalog one binder page, storage box, shelf, or display case at a time. Give the batch a temporary label so uncataloged items do not get mixed back into completed work.
CollectAIO Guides
A useful catalog starts with exact identity, not a portfolio total.
Catalog the item you actually own, then attach quantity, condition, cost basis, and notes. A clean inventory makes value checks, insurance records, trades, and sale decisions easier later.

Search one item you own to start tracking it.
Choose the exact item or variation. If you create an account, CollectAIO keeps the tracking intent through sign-up.
Cataloging workflow
Work in small batches and finish each row before moving on.
Ten exact rows are more useful than one hundred vague names. Start with a shelf, binder page, box, or display case you can complete in one sitting.
Step 2
Match exact identity
Record the full name plus the category-specific identifier: set and card number, grade, finish, LEGO set or figure number, mint mark, pressing, sealed format, or retailer exclusive.
Step 3
Record the holding
Add quantity, condition, cost basis, purchase date, and private notes. Use separate rows or units when copies have different grades, conditions, or acquisition costs.
Step 4
Attach evidence last
After identity is settled, connect the row to current value, sold comps, active asks, source guides, and confidence. Never use a broad price to decide which variant you own.
Identity by category
The fields that prevent expensive mixups change by collectible.
A shared portfolio still needs category-specific identity. These are the minimum details worth preserving.
Cards and comics
Set, number, printing, finish, grade
Keep raw and graded copies separate. Record foil, holo, parallel, promo, retailer, language, edition, cover, and printing details when they create distinct markets.
LEGO, toys, and figures
Set or figure ID, completeness, packaging
Separate new sealed, used complete, incomplete, loose complete, and packaged figures. Accessories and box condition can materially change the comparable market.
Coins, records, and sealed products
Issue details, pressing, format, provenance
Preserve year, mint mark, certification, pressing identifiers, region, edition, box format, case quantity, and retailer tags before using a price from a similar-looking item.
Minimum record
Every catalog row should answer six questions.
Add optional fields only after the core record is consistent.
- 1What is the exact item and category?
- 2Which variation, printing, grade, condition, or sealed format is it?
- 3How many copies or units do you own?
- 4What did each copy cost, and when was it acquired?
- 5Where is the item stored, and what private note matters later?
- 6Which dated market evidence supports the current value?

FAQ
Questions collectors ask before they start.
What is the fastest way to catalog a large collection?
Work in physical batches and finish exact identity before adding market values. A barcode or photo can speed lookup, but ambiguous results still need a set number, figure ID, grade, finish, or other category-specific check.
Should duplicate collectibles share one row?
They can share one quantity when the copies have the same identity, condition, and cost basis. Use separate units or rows when condition, grade, acquisition cost, or sale status differs.
Do I need to photograph every collectible?
Not always. Photos are most useful for condition, signatures, serial numbers, packaging damage, provenance, and items that are difficult to identify from a catalog reference alone.
Should I value items while cataloging them?
Only after exact identity is confirmed. Cataloging and valuation are separate passes because searching for a price too early can anchor the row to the wrong variant.
