I was in a similar dilemma last year. After having a dormant collection for 15 years, I found myself getting back into the hobby by acquiring some pre World War II graded baseball cards. I then made the decision to streamline my collection by selling the bulk of my dormant collection to some coworkers and collect cards in which I had a specific interest. This in turn freed up some space in my house!

I then took the money from the cards that I sold, and purchased some T206, T205, and some Goudey and Playball cards. I concentrated on the cards from the 1930's and 40's as that is my favorite era in baseball. I have flipped and traded cards in the past, but the ultimate high for me was when I used the money that I got from selling my collection and searched and won auctions for a Matthewson and a Ruth card among others. Will I do this again in the future? Probably not but you never know!
