I have noticed a rather disturbing trend. As the economy turns for the worse so does the honesty of sellers. As far as bottles and glass is concerned, know what you are selling. There are plenty of online resources to help you before you list and the literature available could fill a nice sized library. Just because your bottle has a "cork top" does not mean it's "very rare" or "200 plus years old". Do a little research.

Cork closure, seam all the way to the top= 1920 and later

Tooled top, seam just past the shoulder = late 1800s early 1900s

Applied top, seam just past the shoulder = 1870s till early 1890s

Applied top,seam just past the shoulder, iron pontil base = late 1850s till 1860s

Applied top, seam just past the shoulder, open pontil or blow pipe pontil base 1820s till 1850s

This is a very general guide. There are many variables wich vary by geographical location and time line. So be sure what you are selling and don't insult bottle collectors with words like "rare" or "one of a kind" unless you've done the research and know what you have. Trust me, if you list it in the correct category and take clear photos, we will find it and bid it accordingly.
