With toys you have Toys & hobbies, then you also have a category for toys in the Collectible section.
Take oldintheattic avatar pic do you really think that , that Antique Royal Worchester set of around 1923? would be well placed in a category amongst load of modern day cheap China that was run off a chinese production line last month?
IMO there should be a section with the Antiques & Collectibles categories ( in particular the Antiques category) for china & porcelaine..
I as a buyer if looking to buy Antiques, would browse through the Antiques section looking for something that catches my eye..
If I am looking for something specific I will then put a brand name in the search.
