If you’ve come across an old anvil and suspect it’s a Trenton 126lb Mouse Hole Anvil, you’re probably wondering how to confirm its authenticity. Trenton anvils are well-known for their durability and craftsmanship, making them highly sought after by blacksmiths and collectors. But identifying a real Trenton anvil requires checking specific markings, weight indicators, and structural details. In this guide, we’ll walk you through everything you need to know to identify a Trenton 126lb Mouse Hole Anvil and understand its history, value, and key features.
What is a Trenton 126lb Mouse Hole Anvil?
A Trenton 126lb Mouse Hole Anvil is a type of anvil manufactured by the Trenton Anvil Company, a well-known American anvil maker. These anvils were produced primarily in the late 19th and early 20th centuries, making them valuable antiques today.
The term “Mouse Hole” does not refer to the Trenton brand itself but rather to a small hole found on some early anvils, which originated from the Mouse Hole Forge in England. Many blacksmiths mistakenly associate the term with Trenton anvils, but they are two separate things. However, the Trenton 126lb anvil is often compared to Mouse Hole anvils due to similar manufacturing techniques and features.
How to Identify a Real Trenton 126lb Anvil?
Identifying a real Trenton anvil requires careful examination of its stamps, markings, weight, and overall shape. Many counterfeit or misidentified anvils exist, so it’s essential to know exactly what to look for.
Here are some of the key ways to confirm authenticity:
Look for the Trenton Stamp
One of the most crucial identifiers of a real Trenton anvil is the manufacturer’s stamp. The Trenton Anvil Company used a distinct logo, usually located on the side of the anvil.

- The stamp typically features the word “TRENTON” in clear, bold letters.
- Some older models may also include a triangle logo above or below the name.
- If the stamp is worn out, gently cleaning the area with a wire brush can help reveal the marking.
If your anvil does not have a clear Trenton stamp, it may not be an authentic Trenton anvil.
Check the Weight Markings
Trenton anvils, like many other traditional anvils, often have weight markings stamped on the side or base. The weight of a 126lb Trenton anvil should be clearly indicated.
- Look for numbers like 126 or a set of digits that add up to 126 lbs.
- Some older Trenton anvils use the hundredweight system (CWT), which means the weight could be written as 1-0-6 (1 hundredweight, 0 quarters, 6 pounds).
- If the weight marking does not match 126 lbs, it may be a different model or brand.
Examine the Shape and Features
Trenton anvils have a distinctive shape that can help confirm authenticity. Key features include:
- A narrow waist, which gives the anvil a more defined shape.
- A flat, smooth face designed for precision hammering.
- A rounded horn that tapers smoothly for shaping metal.
- A sturdy heel with a hardy hole and pritchel hole.
If your anvil has an unusual shape or lacks these features, it may not be a genuine Trenton anvil.
Understanding the Serial Numbers and Markings
Trenton anvils include serial numbers that can help identify their age and authenticity. These serial numbers are usually found on the front foot of the anvil (the base under the horn).
- The serial numbers are stamped into the metal and can sometimes be difficult to read.
- Using a light rubbing of chalk or a flashlight can help make the numbers more visible.
- You can cross-reference the serial number with an anvil database or historical records to determine the manufacturing year.
If your anvil does not have a serial number, it may be a fake or an extremely early model.
Why Does the Mouse Hole Matter?
The term “Mouse Hole” comes from the Mouse Hole Forge, an old English anvil manufacturer. Many collectors and blacksmiths confuse Mouse Hole anvils with Trenton anvils due to their similar shapes and markings.
However, the Mouse Hole Forge and Trenton Anvil Company are separate entities. Trenton anvils were American-made, whereas Mouse Hole anvils were produced in England. The confusion arises because early Trenton anvils sometimes copied the structural design of Mouse Hole anvils.
If your anvil has a mouse hole but lacks the Trenton stamp, it could be a Mouse Hole Forge anvil instead of a Trenton.
Is Every Mouse Hole Anvil a Trenton?
No, not every mouse hole anvil is a Trenton anvil. Many different manufacturers produced anvils with similar designs. Some popular brands include:
- Mouse Hole Forge (England)
- Hay Budden (USA)
- Fisher Norris (USA)
- Peter Wright (England)
While these anvils share some similarities, a real Trenton anvil must have the Trenton stamp, correct weight markings, and serial numbers.
How Old is Your Trenton Anvil?
The age of a Trenton anvil can often be determined by its serial number and design characteristics. The Trenton Anvil Company produced anvils from the late 1800s to the mid-1900s.

- If your anvil has a low serial number, it was likely made in the late 1800s.
- Higher serial numbers indicate early 1900s production.
- By comparing your serial number with Trenton anvil production records, you can estimate the manufacturing year.
Where Can You Buy or Sell a Trenton 126lb Anvil?
If you’re looking to buy or sell a Trenton anvil, some of the best places include:
- eBay – A popular online marketplace for antique tools.
- Facebook Marketplace – Many blacksmithing groups have members looking for vintage anvils.
- Auction Houses – Some specialized auctions focus on blacksmithing tools.
- Local Blacksmithing Clubs – Great places to network and find buyers/sellers.
How Much is a Trenton 126lb Anvil Worth?
The price of a Trenton 126lb anvil depends on several factors:
- Condition – Anvils with minimal wear and clear markings are worth more.
- Age – Older Trenton anvils may have higher collectible value.
- Location – Prices vary by region due to availability.
On average, a Trenton 126lb anvil can sell for $500 to $1,500, depending on its condition. Some rare models may even fetch higher prices.
Tips for Identifying Your Anvil
- Always check for the Trenton stamp on the body of the anvil.
- Verify the weight markings and serial number.
- Compare the shape and design to known Trenton models.
- Use historical databases or collector forums to cross-reference serial numbers.
- Be cautious of fake or misidentified anvils when buying or selling.
The Bottom Line
Identifying a Trenton 126lb Mouse Hole Anvil requires careful inspection of markings, weight, shape, and serial numbers. While the term “Mouse Hole” is often used incorrectly, a real Trenton anvil will always have the Trenton stamp and distinctive design features. Whether you’re a collector, blacksmith, or antique tool enthusiast, knowing how to verify a genuine Trenton anvil can help you make the right purchase or sale.
