RareBillRadar serial number
The serial reads the same forwards and backwards, like 12344321. The name comes from the word radar itself being a palindrome.
How rare is it? Exactly 9,900 of the 100,000,000 possible eight-digit serial numbers are radars — about 1 in 10,101. That figure is counted, not estimated: every possible serial was run through the same engine the RareBill app uses.
How to spot one
Compare the first digit to the last, the second to the seventh, and so on. If every mirrored pair matches, it is a radar.

What it is worth
The most recognised fancy serial after the solid, and the one most likely to sell quickly because buyers understand it at a glance.
Condition matters as much as the pattern. A crisp uncirculated note can be worth many times the same serial in worn condition, which is why RareBill shows value ranges with links to current listings rather than a single number.

Among the sixteen patterns RareBill checks, radars rank #10 by scarcity.
Only true binaries, seven-of-a-kinds, low serials are rarer among the patterns RareBill checks.
