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 Methods Can Be Used to Date a Mills Slot Machine?

Dating a Mills slot machine can be done through several methods. Firstly, examine the machine's serial number, often found on a metal plate or decal, which can provide a manufacturing date. Secondly, the design and style of the machine can offer clues; Mills introduced distinct models like the Castle Front and War Eagle, each with unique features and release dates. Thirdly, the payout mechanism can be indicative; early models used a 'trade stimulator' payout, later transitioning to 'nickel in the slot' machines. Lastly, consult historical records and Mills catalogs, which detail production timelines and model introductions. Combining these methods can accurately date your Mills slot machine.

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.

What Are the Best Slot Machines for Home Use?

For home use, the best slot machines are those that offer a balance of entertainment and practicality. Classic mechanical slot machines, like those from Jennings or Mills, provide an authentic casino feel. Modern electronic slot machines, such as those by IGT or Aristocrat, offer advanced features and better graphics. Consider machines with adjustable paylines and bet sizes to cater to different players. Ensure the machine is legal for home use in your area and comes with a warranty.
