Frequently Questions

How Can I Determine the Age of a Mills Slot Machine?

Determining the age of a Mills slot machine involves examining several key identifiers. Check the castings and moldings for a date stamp, often found on the back casting or the bottom of the machine. Mills machines produced before 1910 typically have a single-digit date code, while those from 1910 to 1930 use a two-digit code. Additionally, look for a serial number on the back casting, which can be cross-referenced with Mills records. The machine's design and features, such as the use of cast iron versus wood, can also provide clues. Consulting with a slot machine expert or using online resources like the Mills Slot Machine Collectors Club can offer further assistance.

What is the current value of a Mills slot machine?

The current value of a Mills slot machine varies significantly depending on its condition, age, and rarity. Generally, these vintage machines can range from $500 to $5,000 or more. Factors such as the machine's model, whether it's fully restored or in original condition, and its historical significance all influence its price. Collectors often seek out Mills slot machines for their iconic design and mechanical craftsmanship, making them a prized item in antique gaming collections. For the most accurate valuation, consulting with a specialist in antique slot machines or checking recent auction results is recommended.

 

How much are Mills slot machines worth today?

For instance, a fully restored, early 20th-century Mills Novelty Company machine might fetch around $10,000 to $20,000. However, less pristine or more common models could be priced between $500 and $5,000. The value is influenced by factors like the machine's age, original features, and any unique design elements. Collectors and enthusiasts often seek these vintage slots for their nostalgic appeal and craftsmanship.

The most valuable antique slot machines often include rare models from the early 20th century, such as those made by Mills Novelty Company and Caille Brothers. Notable examples include the Mills Castle Front, a 1905 model known for its intricate design, and the Caille Peerless, a 1907 machine with a distinctive cast iron frame. These machines can fetch hundreds of thousands of dollars at auctions due to their historical significance and scarcity. Other high-value antiques include the Jennings Little Duke and the Pace Comet, both of which are sought after by collectors for their unique features and early production dates.
