toys from childhood Unhealthy?

Ok so a while back I remember wanting to do the baby doll that represents yourself thing. I couldn't find any I liked or they were to expensive. I never got around to it.
I have recently been searching on ebay for childhood toys and things and it has become quite addicting and I am not sure now if wanting these toys or getting them is or isn't healthy.
Does anyone have any input?

I did this a few years ago as well ( maybe 10 years ago) and I re sold most of them on ebay like an idiot cause I want the back. The other things burned up in the fire.

Is craving something from your childhood when you didn't have a good one unhealthy? Is going through with it and buying them unhealthy?
I guess in a way I feel like they will fill a void or bring me happiness. I now they won't complete me or make my life better but I want them!
I already bought something that I had when younger that I adored and am waiting to find the other one of this same thing I had. When it arrived I cried and now sleep with it most nights.

I am not obsessive yet. I only have one thing, but I do also tend to pick out dolls, and vintage toys even if I didn't ever have them when I am at a garage sale or something.
I am not a hoarder yet, I don't even have enough to fill up a shelf although maybe if I didn't have the fire I might.
I don't want to end up on my strange addiction.
I will only buy it is it really calls to me .
Someone just tell me if this is unhealthy or not.
