Recently I picked up a couple of TOS VHS tapes from the early 80s at a flea market. One is from 1980, "Star Trek Volume 2: Amok Time/Journey to Babel"; the other is from 1982, "Star Trek: Space Seed" (box reads "The Episode That Inspired 'STAR TREK II: THE WRATH OF KHAN'" and the issuing company is Paramount Gateway Video). Are these at all collectible, or are they just interesting curios?
