"In 1986, the incremental or flyaway cost for the AH-64A was $7M and the average unit cost was approximately $13.9M based on total costs." [1]

"A new AH-64E has a base flyaway cost of $35 million to $50 million, but international packages often exceed $100 million." [2]

So probably slightly older models.
