Which $100 Note Serial Numbers Are Valuable?

Try this:

You will mainly be looking for first and last prefixes.
In particular first and last prefixes from the 1990s. Some of them are quite valuable in even circulated condition.

prefixes are available here

or you could buy a coin and banknote catalog (rennicks or McDonalds)which will also provide the prefixes.

Any test notes would be great, but first or last prefixes would be awesome!

Sort of like this one that I got from a bank recently when getting cash for an overseas trip. Did I do a double-take when I first saw this? You bet!

That's the stuff of dreams! My biggest problem with noodling $100 notes is that it depletes my bank account very, very quickly, so I'm constantly having to wait until my next pay day to get another batch.

Many of the notes I did get have now been converted into $1 and $2 coins, but I'm unable to return them because I still haven't checked them for varieties and errors.

The only interesting find I have so far is a first prefix $50 note from 2006, but based on Maccas and Renniks, it isn't worth anything.
