Read the sentence.

the fake, counterfeit money, which isn't valid, was discovered in the crime investigation.

what is the best way to revise this sentence to eliminate wordiness?
the money is not valid because it was counterfeit and discovered in the crime investigation.
the counterfeit money was discovered in the crime investigation.
discovered in the crime investigation, the counterfeit money was fake.
the sentence is correct as written.

The counterfeit money was discovered in the crime investigation.

This is the best way to rewrite the sentence because this option gets rid of all redundant words. The definition of "counterfeit" already indicates that the money is fake, and that it is not valid. Therefore, it is better to eliminate these words as they only restate information we already have.

The sentence that is correct would be:

The counterfeit money was discovered in the crime investigation.

The other options have too much wordiness and redundancy. For example, the original sentence has too many descriptions of the phrase "counterfeit money." You already know that counterfeit money is fake and not valid, there is no need to add those extra descriptions.
