So I have some of my old doll boxes (I keep the clothes of the girls in them). I was going through them and I noticed that Molly's (my newest historical... not counting Nellie or Elizabeth... of the original line). Had a box that said made in Germany, USA and China, listed somewhat like that. and the same is said for my Josefina Box (of the ones I have), but my Kailey and Nellie boxes say Made in China only. What does this mean when it comes to the quality of my dolls, or their origins... possibly their ages (when they may have been made).
