You've seen them in old movies, tucked into the corner of a smoke-filled saloon or glowing in the back of a vintage candy shop. The Mills Extraordinary isn't just a prop - it's one of the most sought-after antique slot machines in American history. For collectors and gambling history enthusiasts, finding a Mills Extraordinary in working condition is like uncovering a time capsule from the golden age of mechanical gaming.
Why the Mills Extraordinary Became a Collector's Grail
The Mills Novelty Company of Chicago didn't just manufacture slot machines - they defined the industry standard for nearly five decades. The Extraordinary model, produced primarily in the 1930s and 1940s, earned its name through engineering that was decades ahead of its competitors. While other manufacturers were still using simple clockwork mechanisms, Mills implemented a complex jackpot system with visible coin reserves that let players see exactly what they stood to win.
What separates the Extraordinary from run-of-the-mill antique slots is the gooseneck coin entry and the distinctive bell that rings on substantial wins. That sound became so recognizable that it shaped how later electronic machines designed their audio feedback. You aren't just buying a machine; you're acquiring a piece of engineering that influenced every slot game that followed.
Key Identifying Features
Legitimate Mills Extraordinary machines carry specific markings that separate them from reproductions. Look for the serial number stamped on the mechanism frame - typically six digits starting with a 2 or 3 for models from the 1930s. The original cabinets use quarter-sawn oak rather than the red oak found in many reproductions, giving the wood grain a distinctive tiger-stripe pattern. The award card, displayed behind glass on the front panel, should show original payout amounts matching the machine's denomination configuration.
How Mechanical Payout Systems Actually Worked
Before random number generators and microchips, fairness depended entirely on mechanical precision. The Mills Extraordinary uses a system of notched discs called star wheels, each connected to a specific reel. When you pull the lever, a clockwork spring releases energy that spins all three reels simultaneously. The star wheels determine where each reel stops, with specific notches aligned to create winning combinations.
The brilliance of the design lies in the jackpot mechanism. A separate tube holds coins above the main hopper, visible through a glass window. When three Liberty Bell symbols align (or the top award symbol for that specific machine), a trip lever releases the entire contents of the jackpot tube into the payout tray. Players could watch their potential winnings build over time, creating the same psychological pull that progressive jackpots use today.
Understanding this mechanism explains why maintenance is critical for collectors. A single bent star wheel tooth can throw off the entire payout percentage. Original machines operated at roughly a 75% return-to-player rate - generous for the era but dependent on precise mechanical calibration.
Legal Considerations for Antique Slot Ownership
Here's where things get complicated. Owning a Mills Extraordinary isn't automatically legal just because it's an antique. Federal law permits ownership of machines that are genuine antiques (typically 25+ years old), but state regulations vary dramatically. In states like Nevada, New Jersey, and Louisiana, private ownership is straightforward with minimal paperwork. California allows ownership but restricts possession of functional machines in certain counties.
The trickiest situation involves states where any gambling device is prohibited regardless of age. Utah, Hawaii, and Tennessee maintain strict bans with real legal consequences. Before purchasing any antique slot, verify your local regulations - ignorance isn't a defense, and customs officials do seize machines being shipped into restricted states.
Most serious collectors deactivate the coin mechanism and use their machines as display pieces. This doesn't diminish value significantly for machines already in collections, though serious buyers still prefer fully functional units. Documentation of deactivation can actually simplify shipping and insurance.
State-by-State Quick Reference
| State | Ownership Status | Age Requirement | Notes |
|---|---|---|---|
| Nevada | Fully Legal | None | No restrictions on private ownership |
| California | Conditional | 25+ years | County regulations may apply |
| New York | Legal | 30+ years | Must be non-operational in some municipalities |
| Utah | Prohibited | N/A | Complete ban on all gambling devices |
Restoration vs. Preservation: Making the Right Choice
That Mills Extraordinary you found in a barn isn't automatically a candidate for full restoration. Over-enthusiastic refinishing has destroyed more collector value than neglect ever did. Original paint, even when faded, carries significant premium over repainted surfaces. Those scratches on the cast iron front aren't damage - they're provenance, showing the machine's working history.
Professional restoration should focus on mechanical functionality rather than cosmetic perfection. The clockwork mechanism needs cleaning and lubrication with period-appropriate materials - modern synthetic lubricants can actually damage brass gears designed for whale oil based solutions. Finding a technician who specializes in vintage Mills machines is worth the premium over general antique restoration services.
Replacement parts present another decision point. Original Mills parts command substantial prices - a complete set of original reel strips can cost $400-600. Reproduction parts are widely available and mechanically functional, but serious collectors can spot them immediately. Your choice depends on your goals: machines for display can use reproductions freely, while investment-grade pieces need documented original components.
Current Market Values and Where to Find Machines
Prices for Mills Extraordinary machines have stabilized after a peak around 2018, though exceptional examples still command premium prices. A fully functional, documented Extraordinary in original cabinet finish typically sells between $2,500 and $4,500. Machines with unusual configurations - such as 5-cent denominations or rare award card variations - can exceed $6,000 at specialized auctions.
eBay remains surprisingly viable for slot machine purchases, but buyer protection is limited for items this expensive. Dedicated auction houses like Victorian Casino Antiques and Slot Machines Unlimited offer authentication services and ship internationally. Private sales through collector networks often yield the best prices but require established relationships.
Watch for machines being sold as "Mills Extraordinary" that are actually Mills Futurity or Mills Jewel models with swapped faceplates. The Extraordinary has a distinctive rectangular jackpot window on the upper right - other models positioned this differently or omitted it entirely.
Red Flags When Evaluating Purchases
Several warning signs indicate potential problems. A machine that hasn't been powered or operated in decades may have seized mechanisms that require complete disassembly - budget $800-1,200 for professional repair. Serial numbers that don't match between the cabinet and mechanism frame suggest mixed components from multiple machines. Repainted cabinets almost always hide structural damage or wood rot beneath new finishes.
Maintaining Your Machine for Long-Term Value
Antique slot machines aren't set-and-forget collectibles. The mechanical systems require exercise - running a machine through several cycles monthly keeps lubrication distributed and prevents spring fatigue. Storage in climate-controlled environments is essential; humidity fluctuations cause wood cabinet warping and brass mechanism corrosion.
Coin quality matters more than you might expect. Period-correct coins feed properly through original mechanisms, while modern reproductions often have slightly different metallurgical composition that can jam the hopper. For a Mills Extraordinary designed for nickels, sourcing rolls of Buffalo nickels or pre-1938 Jefferson nickels provides both authentic operation and display appeal.
Insurance requires specific antique slot machine riders on your homeowner's policy. Standard policies often exclude gambling devices entirely or cap payouts well below actual replacement value. Document your machine with detailed photographs of the mechanism, cabinet, and serial numbers before any issues arise.
FAQ
How much is a Mills Extraordinary slot machine worth?
Working models in original condition typically sell for $2,500-4,500, with rare configurations or exceptional provenance pushing values to $6,000 or higher. Non-functional machines needing restoration usually trade at $1,000-2,000 depending on completeness of original parts.
Can I legally own an antique slot machine in my state?
It depends entirely on your state. Nevada, New Jersey, Louisiana, and most states allow private ownership of machines over 25 years old. Utah, Hawaii, and Tennessee prohibit all gambling devices regardless of age. Check your specific state's current regulations before purchasing.
Where can I get parts for a Mills slot machine?
Several specialty suppliers manufacture reproduction Mills parts, including Slots of Montana and Antique Slot Machine Store. For original components, collector forums and specialized auctions remain the primary sources. Expect to pay significant premiums for documented original parts.
Do antique slot machines pay out real money?
When functional and loaded with coins, yes - the mechanical systems still operate the same way they did in the 1930s. However, most collectors either deactivate mechanisms or display machines unloaded. Using any gambling device for actual wagering may violate local laws regardless of the machine's age.
How do I tell if a Mills Extraordinary is authentic?
Check for matching serial numbers on the mechanism frame and cabinet interior, examine the wood grain for quarter-sawn oak patterns, and verify the award card matches the machine's denomination. Reproductions often use red oak, lack internal serial stamps, or have anachronistic payout information on award cards.
