There's no simple answer but instead, as I suggested before, there are general guidelines. And one of the axioms of bottle collecting is that there are multiple exceptions to every rule of thumb.
The problem with using eBay is that there is a mountain of stuff there which is listed but never sells. Add to that - a single item sold is not a guide but not a true statement of value. Add to that, there are literally thousands upon thousands of different bottles such as yours. Almost certainly, you will find similar but not exact matches to what you have.
If you want to use eBay, be sure to focus on the items which have actually sold.
If you would like to compare one of your bottles to one that sold on eBay, I am glad to address the comparison and get a bit specific about the similarities and differences of the two from a value perspective.
