Seeds
Chinese porcelain ginger jars
Vintage Polynesian cocktail mugs (Tiki stylee)
Copper cookware
Kitchen gadgets
Vintage 1950s and 60s cookbooks (happy homemaker crap)

Stuff I'd collect if I had more money-
Eskimo soapstone carvings
Japanese netsukes
(I have a few of both but they are outrageously expensive)
