How to Identify an Old Bottle and Find Its Value
Finding an old bottle can be exciting, but identifying exactly what it is—and what it may be worth—can take some research. Small details such as embossing, maker names, bottle shape, colour, seams and base markings can all provide clues.
The best way to identify an old bottle is to examine it carefully, record the markings you can see and compare those details with known bottle makers, styles and sales of similar examples.
1. Check for Embossed Names and Lettering
Start by looking for any wording moulded into the glass or stoneware. Embossed names are often one of the most useful clues when identifying an old bottle.
Look for:
- Company or maker names
- Town, city or region names
- Product names
- Advertising text
- Patent details
- Registered trade marks
Photograph the embossing clearly, especially if some letters are worn or difficult to read.
2. Examine the Base of the Bottle
The base may contain numbers, letters, logos or other maker marks that help identify who produced the bottle or when it was manufactured.
Check for:
- Maker symbols
- Mould numbers
- Date codes
- Letters or initials
- Manufacturing marks
A clear photo of the base can sometimes provide information that is not visible from the front of the bottle.
3. Look at the Bottle Shape and Top
Bottle shape and closure style can provide clues about the original contents and approximate age.
Features to examine include:
- Crown tops
- Corks
- Screw tops
- Blob tops
- Internal-thread closures
- Stopper styles
- Neck shape
- Body shape
Some bottle types were associated with particular products, industries or periods.
4. Check the Colour and Glass
Colour can also help narrow down an identification. Old bottles can appear in clear, aqua, green, amber, brown, cobalt blue and many other shades.
Colour alone does not determine age or value, but unusual colours can sometimes make particular bottles more desirable to collectors.
5. Examine Seams and Manufacturing Marks
Mould seams and manufacturing marks can help provide an approximate indication of how a bottle was made.
Look at where the seams run and whether they continue up the neck or finish below the top. The base may also show signs of the manufacturing process.
These details are most useful when considered together with the bottle’s shape, maker and other markings.
6. Identify the Maker or Company
If the bottle has a readable company name, research the business and where it operated.
Useful information can include:
- Years the company operated
- Locations or branches
- Products it sold
- Changes in company name
- Different bottle styles used over time
This can help narrow down the approximate age and origin of the bottle.
7. Research What the Bottle Was Used For
Old bottles were used for many different products, including:
- Soft drinks
- Beer and brewing
- Milk and dairy products
- Medicines
- Condiments
- Mineral water
- Ginger beer
- Chemicals
- Household products
The bottle’s shape, wording and closure can often provide clues about its original contents.
How to Find the Value of an Old Bottle
Once you have identified the bottle, the next step is to look for comparable sales.
Recent sold listings are generally more useful than current asking prices because they show what buyers have actually paid.
Try to compare bottles with the same:
- Maker
- Type
- Age
- Colour
- Size
- Embossing
- Condition
If you cannot find an exact match, use the closest comparable examples available and treat the result as an estimate.
What Makes an Old Bottle Valuable?
Several factors can affect bottle value at the same time.
- Rarity: uncommon makers, varieties or colours may attract more interest.
- Condition: chips, cracks, staining and damage can reduce value.
- Age: older does not automatically mean more valuable, but age can be important.
- Maker: some companies and regions are more collectible than others.
- Embossing: strong advertising or unusual wording can increase collector interest.
- Colour: unusual colours may be more desirable.
- Demand: values depend on what collectors currently want.
Use a Bottle Identification App
If you have an old bottle but are unsure what it is, a bottle identification app can help give you a starting point.
Bottle Collector lets you photograph an old or antique bottle, review identifying details, research its history and estimate its value before saving it to your collection.
The app can be useful for antique glass bottles, ginger beers, stoneware, milk bottles, brewery bottles, soft drink bottles, embossed bottles and other collectible containers.
Take Clear Photos for Better Identification
When photographing a bottle for identification, include several clear views rather than just one image.
- Photograph the whole bottle
- Take a close-up of any embossing
- Photograph the base
- Include the top or closure
- Capture labels or advertising
- Use good lighting
- Avoid glare where possible
Clear photos make it easier to read markings and compare the bottle with known examples.
Save What You Learn
Once you have identified and researched a bottle, keep the information with the bottle rather than having to research it again later.
Bottle Collector can save the bottle name, maker, approximate age, region, category, history, estimated value, photos and personal notes as part of your collection.
