ebay isn't the place for price information that it was a few years ago imo, there are specialized card sites that are much more accurate.
As for Jeter rookie cards their value peaked in the days before and after his 3000th hit. Its best to sell when there is hype. It's also best to sell just before they retire. Early baseball cards will only gain in value but the divide between early and current grows every year and those cards are less rare and harder to sell to someone who never saw him play.
My nephew asked me who Cal Ripkin was last year, it made me shake my head. he had looked up the iron man movie on Google and wondered why Cal showed up...
