Here is what makes 7 of a kind "rare".  United States currency is printed in in runs of 96 million.  If more of a given series is needed then the suffix letter, which starts at "A", is incremented to the next letter.  United States currency also shows preceding zeros in the serial numbes.  EG: 00000001 and so on.  What this means is there are 72 instances for numbers 0 to 8 for a subtotal of 648 "7 of a kind's) plus another 6 for the 9 digit totalling 654.  This means out of 96 million serial numbers only 654 can be a "7 of a kind", OR restated: there is a 0.00068125% chance of finding such a bill.

Sidenote on the number 9:  Because there are 96,000,000 notes per suffix the 2nd digit can not be a 9 (or 8,7) and when it is a 6 there are only zeros behind.  As such there can only be a 0, 1, 2, 3, 4, or 5 thus making the 6 possible "7 of a kind" options for the starting digit of 9.

Sidenote on the odds: The chance of being hit by lightning (the universal "chance of" comparison) is 1:15,300, or recalculated: 0.00653595%.  MEANING the chance of being hit by lightning is  959.4 times more likely than finding a "7 of a kind" note.
