The Interesting History of Door Knobs
The onset of the 19th century gave rise to the era of vintage door knobs. The earlier models were mostly made from strong metals, such as brass or bronze, that serve fundamental functions.
These knob designs were pretty simple before they were merged with ornate designs and intricate patterns in the Victorian era. These decorative elements were made from expensive materials like porcelain, gold, and crystal.
Soon, the Edwardian period followed, when the antiques became less flashy and more classy with limited motifs, shifting their purpose from luxury to decor. Unlike the Victorian era, even the middle class could afford it.
Finally, it was World War I when glass door knobs replaced metals like steel due to rationing. Even so, the knobs were impressively strong, so much so that some made it to the present era.
Main Types of Vintage Door Knobs (With Values)
We can categorize door knobs mainly into two categories:
1. Commercial Door Knobs
Commercial door knobs are customized with monograms, initials, and logos to help with the brand’s identification and promotion. This type of door knob can be professional as well as personal, costing between $50 to $100 or more.
2. Residential Door Knobs
These types of knobs are more personalized (than custom-made) as they represent the style and choice of the residence’s owner. The average price of a residential door knob would be approximately around $12 to $200, as the unique designs may cost more.
