Your total collection value is the sum of the current market price for each card in your inventory. Here's how it works under the hood.
Where prices come from
Cubbby pulls pricing from live market data:
- Completed sale listings, real sale prices from actual transactions between collectors. This is our primary source because it reflects what people are actually paying right now.
- Live market price feeds, comprehensive pricing data that aggregates market activity across multiple platforms.
We prioritize completed sales over listings or price guides because they represent real market value, not what sellers are hoping to get.
For more detail on individual card pricing, see How Cubbby card values work.
How often prices update
Market prices refresh automatically in the background. Cubbby takes a weekly snapshot of owned card values, with on-demand refreshes when a card needs updated pricing. Those saved snapshots are how the value chart on your dashboard is built.
Individual card values can also update when you view a card's detail page. If a tile and detail page disagree, see Why can tile and detail page prices differ?.
Grade-specific pricing
A PSA 10 and a raw copy of the same card can have dramatically different values. When you set a grade on a card (e.g. PSA 10, BGS 9.5), Cubbby looks for sale prices specifically for that grade. Always make sure your card's grade is set correctly for the most accurate valuation.
Purchase price vs market value
Cubbby tracks two numbers for each card:
| | Description | |---|---| | Purchase price | What you paid for the card (you set this when adding) | | Market value | The current sale price based on recent completed sales |
The difference between these is your gain or loss, shown on each card's detail page. This lets you see at a glance which cards have appreciated and which have declined.
Portfolio value over time
Your dashboard shows a chart of your portfolio value history. Cubbby records scheduled weekly snapshots and can add fresh snapshots when cards are refreshed, so you can track performance over 1 day, 1 week, 1 month, or 90 days.
Why is my card showing no value?
A card might show $0.00 or no value for a few reasons:
- No recent sales data. The card hasn't sold recently or doesn't yet have live market pricing available
- Rare variant. Very niche parallels or error cards may have too few sales to price accurately
- Grade mismatch. There may be sales data for the raw version but not your specific grade
The card is still in your collection and will update automatically when pricing data becomes available.
