If I was in your shoes, I'd be tempted to keep the best example of the lot, and spend the rest.
So far, the key star note and only short run star for this series and denomination is MB03200001* to MB03840000*...this serial number range was printed as sheet replacement notes and usually turn up two in a pack of non-star notes. Run collectors wouldn't want or need more than one of the OP's consecutive notes. JMHO
