I've never been a Mets fan, but the 1985 Dwight Gooden was such a hot card at the time, I spent months of trading to finally get one off a elementary school friend of mine and for the longest time considered it my holy grail until I ordered a 1972 Willie Mays from the back of a Beckett Catalogue for $12
at the age of 9.
That remained my favorite for years to come.
