Fancy Serial Number Checker

Type the serial and choose the denomination. Letters at either end are ignored. The checker names the pattern from the types listed here, and the published green-seal range shows when the guide prices it.

Serial number

Letters before or after the digits are fine. The check reads the eight numbers.

Types of fancy serials

A fancy serial is a pattern in the eight digits. Letters at either end, and a star, do not change the pattern. The checker names these types. Choose the denomination to see a published green-seal range when the guide prices that type. A plain radar, repeater, or binary is still a find, and that guide does not price it.

Also collected
