RareBillSuper radar
A radar whose middle six digits are all identical: 70000007. It reads the same in both directions and has a solid block in the centre.
How rare is it? Exactly 90 of the 100,000,000 possible eight-digit serial numbers are super radars — about 1 in 1,111,111. That figure is counted, not estimated: every possible serial was run through the same engine the RareBill app uses.
How to spot one
Confirm it reads the same backwards, then check that everything between the first and last digit is one repeated digit.

What it is worth
Considerably more than a plain radar. The visual effect is striking, which matters more to buyers than the arithmetic does.
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.
Where it sits
Among the sixteen patterns RareBill checks, super radars rank #4 by scarcity.
Only ladders, solids, super repeaters are rarer among the patterns RareBill checks.
