Super Radar Notes
The inner six digits form a palindrome — related to the Radar but distinct, and often confused with it by newer collectors.
A Super Radar note has a serial number in which the inner six digits (positions 2 through 7) form a palindrome — meaning they read the same forwards and backwards — even though the full 8-digit serial is NOT itself a palindrome.
Verified example: 01233215
- Inner 6 digits (positions 2–7):
123321→ reversed:123321✓ (palindrome) - Outer digits: position 1 =
0, position 8 =5→ 0 ≠ 5, so the full 8-digit sequence is not a palindrome ✓
This means the note qualifies as a Super Radar but would NOT qualify as a full Radar.
Distinguishing From Radar
A Radar note has ALL 8 digits forming a palindrome (e.g., 12344321). A Super Radar has only the INNER 6 digits palindromic, with the outer two (first and last) being non-matching. This makes Super Radars more common than full Radars but still quite rare.
If a note is a full Radar, it is NOT also a Super Radar in our classification — a full Radar is the superior category. Super Radar is only applied when the inner 6 form a palindrome but the full 8 do not.
Rarity and Value
Super Radar notes occur approximately once in every 10,000 notes — similar frequency to standard Radars. In circulated condition, they typically sell for $15–$75; in uncirculated condition, $50–$200. They are less well-known than standard Radars, which can mean savvy buyers find them at lower prices from sellers who don't recognize the pattern.
