Beer Stein Collectors

My girlfriend has a lot of pitchers of beer to his mother collected by him, for some reason, and now they want to sell
His mother said that most of them are worth much money, i was just going to sell on eBay but I think I can get more if I sell them to collectors. Any idea where or what I have to do to sell? I know nothing about beer mugs, someone please help!
I would go with eBay to ensure that our clear boxes
