Find the prices of old soda bottles on the iGuide website or by searching books dedicated to providing price lists for old bottles, such as the “Antique Trader Bottles Identification and Price Guide” or “The Standard Old Bottle Price Guide.” The iGuide website has a section dedicated to old bottles that is populated with the site's proprietary Real Market Data.
IGuide's Real Market Data pricing provides updated information on what users should pay for specific items. The search system uses real market data based on data and sales gathered from auction sites. Its name comes from the fact that data collection occurs in real time. The goal of this system is to provide the most accurate pricing for items quickly. While iGuide tries to provide accurate values of old soda bottles, the site states that the value of a bottle is only as high as what an individual is willing to pay, so while the values are based on what people have paid, it doesn't guarantee the same prices for its users.
The “Standard Old Bottle Price Guide” provides prices for old soda bottles and for mineral water, ale, beer, medicine and other old bottles. While this particular book is only available in paperback on Amazon as of January 2016, the “Antique Trader Bottles Identification and Price Guide” is available in paperback and as a digital download for the Amazon Kindle.
