That is what is called a torpedo bottle. It could have had soda, beer, etc. in it. Most likely soda. In my non-professional opinion, I would say that's worth about $10-$15.
I think these most commonly had ginger ale in them and came from the UK. Without any embossing I'd place the value more around $5-10, or really whatever someone is willing to pay. They're fairly common.
this bottle is a round bottom . a torpedo ginger ale comes to a point at the bottom . never the less you have a nice one . the stranger version of this bottle is with a crown top .
