Nicknackitarian [noun] A dealer in curiosities. Mentioned with the definition: mummies, and arrows dipped in the poisons of upas-tree, as well as bows, antique shields, helmets, etc.
Basically, people who sell the best tchotchkes. I have no idea where or when you will use this word, but I knew I wanted to give it its moment in the light.
