Hi, I just thought this may be interesting for anyone who wants to know about US replacements (they use a "Star").
Here is what it says on the original banding of the notes:
"If the numbers on notes in this package do not run in sequence, the substituted notes are indicated by a "Star". Inquiries should include the series and serial numbers, to include the suffix letters of the notes."
It's like they are asking for people to find out about them!
I am not really sure how rare star notes are, but I have only seen 3, mind you I handle much less US currency.
