Hi Kathy, I do not know about value... I would guess that the ebay piece is a little high.... I like your piece better. If I was bidding at auction, which is how I buy most of my stuff, I would expect to be in the $300-400 range to buy it, as long as there is no damage to it of any kind, other than maybe some light wear to the finish which is mostly expected. IMHO I would date it, based on the use of Nouveau appearing whips and the non-linear vase form to be in the 1890-1900 range. Ask the Harrach project and see what they say..... Some internet sites will not give values, but will help to date the piece....
Keep me posted.....
