There are three bottlings (but probably many more formulations) of the Opium EDT. The original, circa 1977:
The 2003 revamp, coinciding with the release of the Eau de Parfum (in the gold box):
And of course, the latest offender, circa 2009:
The black collector's edition bottle you're referring to came out in 2006, I believe, and (one assumes) is the same formulation as the 2003 edition.
From what I've gathered reading umpteen online discussions of the topic, the 2009 formula differs dramatically from the 1977, but less so from the 2003. Opinions vary as to just how much Opium has changed/suffered over the years.
