Thanks revert,
I coughed up the member fee and subscribed to the GPA Analysis site yesterday. Very interesting info to say the least.
I see the major difference in prices of graded Vs. non graded. I'm heading out to FloridaSupercon today and will be dropping off 5 books to the CGC booth to be graded. I've guesstimated the grades. Hopefully I'll be pretty close on the estimates (each purposely in different conditions); that way I will be able to get a sense of the rest of the collection.
When I referenced to if I should sell, simply meant the "True Value/ ROI" of my comics i.e cost of packaging/shipping/ grading/ commissions etc. Vs. potential sale value Vs. value of time (price history trends. Are values steadily increased, are they inflated, have they decreased etc.).
As far as my personal preferences, obviously theres an emotional connection solely based on it being a hobby I did as a kid. Regardless of selling or not theres certain books I'd keep (Incredible Hulk 181 for example, as Wolverine was my favorite character growing up). That being said, I live in the world of investments and whenever I have a commodity in hand I have to understand it's value, risk vs reward etc.
Thanks for the info on the subform. I very much appreciate you taking the time to answer my question too.
