A record sale is a historical fact
When a verified buyer and seller complete a transaction, the result belongs in the sales history. It may establish a new high for that exact card, grade and certification. That is different from claiming the next copy will sell at the same price.
Market value needs repeatability
A useful market estimate usually combines several recent sales, gives more weight to current transactions and removes obvious misclassified listings. PriceCharting describes using recent price, median, average, age weighting and outlier review rather than copying the single highest result.
Rare assets need a wider evidence file
When no close comparable exists, inspect provenance, certification, population, auction venue and previous transactions for the same copy. A trophy card sold by a major auction house has a different buyer pool from an ordinary marketplace listing.
Common mistakes
- Applying a PSA 10 result to a raw card.
- Comparing English and Japanese printings without saying so.
- Using an asking price instead of a completed sale.
- Ignoring buyer premiums and transaction dates.
- Calling one sale a trend.
The wording Celeste will use
We will say sold for when a transaction is documented, market estimate when several comparisons support a range, asking price when no sale occurred and insufficient data when the evidence does not justify a number.

Frequently asked questions
- What is the difference between record sale and market value?
A record sale is the highest documented transaction. Market value estimates a repeatable current price using comparable sales.
- Can an auction record be excluded as an outlier?
It can remain a valid record while receiving limited weight in a broader market estimate.
- Are listing prices evidence of value?
They show seller expectations. Completed sales show what a buyer actually paid.
