About 60% of them are from the time period 1930-1960.
That sounds like a good collection to me.

I also have all seasons and the one-hour specials of "I Love Lucy," all seasons of "Full House" (except the last one, which comes out tomorrow, I think), the first three seasons of "Gilmore Girls," and a few random DVDs of "The Lucy Show" and "The Andy Griffith Show."
I just love special features on DVDs, like the 2 disc special editions that most DVDs are available in. So a bunch of my movies are those special editions.
