The police wouldn't be anxious if several thousand counterfeit bank-notes were not in circulation.
I'm afraid that this sentence is a literal translation from my mother tongue to English. Especially I don't like "several thousand". How would you express the same thought?
Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.

There's nothing wrong with the sentence - assuming that the cops are anxious, etc.
"Several thousand" is OK.
