No - when I have a number of sets I sell them over time. Meaning that I have sold a number of them over the years - 1, here, 1 there. My personal collection has the ghost and phantom combo set Sure - I was happy with $200 and I let one go there. The next year I sold 1 for 250 . after my 2 sales - have $450 back on my investment - after expenses the other three were basically free. Think of it as dollar cost averaging for selling (vs. buying) It doesn't work for every set but storage, for me , isn't an issue so I have a little longer holding period. Also, t think about what the potential for remakes are (X-wings, falcons, Fire stations, At-Ats, etc.) they are always making another one. Things that appeal a little more to me as an investor are the unique sets - the ghost was more of a unique set in my mind. (And the buy-in price did not hurt either)
