What does the Confidence behind an item’s Alt Value mean?

Alt Value shares a "Confidence" level to capture a range in which we expect an item's dollar value to be accurately predicted. Our proprietary value pricing model incorporates a number of data points, including:

  • The year an item was issued
  • The popularity and liquidity of an item's subject and collection
  • An item's recent transaction history

Our confidence level can be low (red), medium (yellow), or high (green). The higher the confidence level of an item, the more available data there is to support its Alt Value.
