I read this thread today.  I was wondering the same thing.  One week I looked at prices of the Bob Mackie dolls and the prices were very low.  I came back 2 weeks later and the prices bumped up .  I had hoped prices would increase on the dolls that I purchased but they are all about the same as when I bought them 5 yrs ago.  Yes, I think these were so over=produced they became worth very little. What I hate doing is keeping them in the shipper and their box, and not enbjoy them because I thought I was preserving value.  There are too many barbie out there.  However I just love some of them.  Just bought a Bill Blass barbie.  Its price was way down. I stuck to ones I liked--harley barbies, coca-cola and a few others/  They still put a smile on my face.  I have about 30--so not a big collection. You are collecting things you like and only buying things you want for yourself. THAT is the way to collect Barbie these days. IMHO you should take those Mackies out of their boxes and DISPLAY them!  =) Enjoy those dolls. The Mackies are one of the few Barbies that MUST be taken out to be displayed so they don't lose as much on the secondary market for being "gently" displayed - i.e. in a case, kept dusted, out of the sun etc. BTW - They will lose some value when you remove them from
