Sports card collecting

I collected only baseball cards in the 70's until 81. I only bought Topps cards and I had complete sets from 73-80. Wish I still had them but not knowing that many of the were worth quite a bit I gave the entire collection to my Pastor's son who was as big of a baseball fan as I was back then. Quite a few of them were actually signed by the players they depicted I had pretty much every Red Sox player during that time period since me and my dad would go to Fenway 3-4 times a year and players would give autographs before the game. I even had a Robin Yount signed rookie card.,
