My collection is not that impressive, but my father has:
1997 OT Widescreen VHS
2000 OT Widescreen VHS
The VCD of the OT (going off of the box, I’m guessing its the same as the 2000 VHS version
2004 DVD set of the OT
2006 GOUT set
DVDs of the prequels and sequels as well as the blu rays for the whole saga.
He also has the DVDs for Rebels, 2008 Clone Wars, 2003 Clone Wars, Droids, Ewoks and a bunch of the Lego Star Wars Series
