These are the exact 4 notes you get, you can let me know if you have any questions.
This is from wikipedia:
A star note is a bank note that has an asterisk (*), or star, after the serial number.
These have been used by various countries around the world including Australia and United States.
In the US, The Bureau of Engraving and Printing inspects currency for printing errors prior to releasing notes into general circulation. When notes are discovered that have been printed incorrectly (such as having the serial numbers upside down, etc.) the misprinted "error notes" are replaced with star notes because no two bills within a certain series can be produced with the same serial number.
They are used to maintain a correct count of notes in a serial number run.
By their nature, star notes are more scarce than notes with standard serial numbers and as such are widely collected by hobbyists.
Some of the highest prices paid for modern (post-1928) U.S. banknotes have been for star notes.
