Radar Serial Number Value
A radar serial number is a palindrome: it reads identically in both directions. 12344321 is a radar, and so is 90055009. The name comes from the word radar itself, which reads the same backwards.
Radars are more common than solids and ladders, which keeps prices moderate, but they are still scarce enough to be worth checking for. There are 10,000 radars per run of 100 million, or one in every 10,000 notes.

Radar versus repeater
These get confused constantly. A radar mirrors: 12344321. A repeater repeats a block: 12341234. Both are collectible and they price similarly, but they are distinct patterns and a note is usually one or the other.
A small number of serials qualify as both, and those are worth substantially more than either category alone because the overlap is genuinely rare.
Super radars
A super radar is a radar whose six inner digits are all the same, with different digits bracketing them: 10000001 or 27777772. These are far scarcer than ordinary radars and are priced closer to the solid and ladder tier.
If your radar has six identical digits in the middle, do not price it against ordinary radar sales. It belongs in a higher bracket.
