I look at a lot of estate sales as well as go to antique stores.
I see Hummels (I always loved them and their story), salt and pepper shaker collections, Sterling silver of all kinds, and silver plate, fine china, action figures, Madame Alexander dolls and other "sets" of collectables.
I had a set of pewter "Precious Moments" gifted to me for several years.
I don't "collect" anything specifit except antique candle molds myself,
and they do have worth, but I love the history of them.
I have one piece of Lladro, a large angel.
