If you are starting to get into the game, or you are already a pro, there are certain tools you might find useful.

1) a counterfeit bill detection system…

a) the first part is a counterfeit detecting felt marker. The chemical in the in detects linen in US currency, and if found, validates the bill as not likely counterfeit. If the bill is largely wood based paper, it will mark darkly, and the color indicates a false bill.
b) a UV detector light. Some bills, US and Canadian bills have both light strips, and/or holographic images that are only visible under the reflection from a UV blacklamp type lamp. This prodcuct comes in counter size, but lately has shown up on market as pen size, that fits in a pocket or attaches as a keychain. I own both and they are highly valueable.
Here is one example:
