Here is my thing.never flipped,always tried to make runs on books.Now that I'm older,consolidation makes sense.I sold my Timely's,JIM'S,and DD"s,but kept my Spidey's,Surfers, and FF's...when the FF movie hits,I'm selling #51-126,and hopefully the rest will keep me happy till I have to dump the good stuff....it's all about timing,but I really want to keep the remaining books to my mid 60's,at least....I look at it as a bump for my SSI,and I'm grateful I bought most of these books at 1/5 of what I paid for.Not quite as good as real estate during that time period,but I can't complain....P.S.I'm 57 and retired...
