Holiday barbie USED to be very sought after and super collectible? Mattell now makes enough to sink a ship? Unless you have a ver early holiday Barboe then the dedication of space isnt really worth it.
I agree. I've seen them on clearance months after the fact.
The value is also in how good of a condition the box is in.
DH's granny gave DD a first edition cabbage patch doll when she was born. The packaging was completely destroyed. The cellophane front was hanging on by a corner and the box was ripped and missing in numerous places. I know that the intention was to be a collectible, but at that point, it really wasn't worth anything. We took it out of the box to let her play with it. It will mean more to her later that it was something that she played with as a child rather than it was something that she could only look at.
I come from a family where everything is collected, and IF you take something out of the box, you do it very carefully, put it on display, and keep the packaging. Treasured beanies, in-box "limited edition" furbies, porcelain dolls (not the cheap kind), Raikes bears, Star Wars toys, Hot Wheels, you name it, it was collected. Most of the time it was put up so that it could collect value and we could sell it later. Never once did we sell any of it. Those Ty/Disney/Warner Bros/Grateful Dead beanies are now tagless and making my child very happy. Same with the furbies. After years of collecting, I've learned that toys are meant to be played with.
If your MIL really wants those to be saved for when she is older, put them in a plastic box, seal it with tape, and put it in the attic/garage/storage building. You can get Barbies for $5-$10.
