You sure have shown us some impressive pieces. Some of these items could very much be worth $$$.00. As For Ebay being the best place, Well I say if it is worth on $$.00 to low $$$.00, then it can be a good way to go, just remember value on ebay is sometimes half, and then with the still lingering Economy the value could go lower. The last piece you have shown us I see the "Beehive" mark. First this mark was used by the porcelain factories in Vienna area, starting from mid 1700's to mid 1800's Then many variations of this mark was used mostly by 6 Factories in the europe area. Just a bit of snooping in the books and the net, appears that could be Ackerman & Fritze, used 1908 to present. Unless yours is a true early Beehive, then you are talking some serious $$$.00. Beware of the Beehive many have been copied a fake, make sure it is Blue mark, under the glaze, always handpainted, thus not asymmetrical. The other point to watch takes a bit of history of the mark. This is a originally a shield, a variation of the coat of Arms of the Hapburg Family but people tended to see it upside down so became a "beehive". So If any other marks are with it, It would be turned as a shield and not a beehive. I would for sure look into this last piece before selling for sure. High end Auction house may be more of what you seek. Still can't make out the marks on the other item. Good mark pics some time takes lots of light a good camera and a steady hand. Mostly Lots of light. I will snoop a bit more on that last item, but we need to figure out if it is Vienna or Ackerman and etc. to really pinpoint this one.
