7 Critical Mistakes to Avoid When Navigating the 2025 Rosemont Chicago Great American Coin Show – A Veteran’s Guide

I’ve watched the same mistakes play out at the Rosemont Chicago Great American Coin Show year after year. Some cost collectors thousands. Others just kill the fun. After decades in the hobby, I can tell you: the best way to survive this show isn’t about what coins you bring—it’s about avoiding the traps most people fall into. Whether you’re a veteran dealer, a serious collector, or just starting out, these seven critical mistakes are what separate a rewarding trip from a regretful one. This is your real-world guide—no fluff, just hard lessons learned the hard way.

1. Assuming All ‘Rare’ Coins Are Authentic (Especially the 1943 Copper)

Let’s be honest: the moment someone says, “I found a 1943 copper penny in Grandpa’s attic!” my Spidey senses tingle. I’ve had collectors walk up to my table with a 1943 copper cent that PCGS already flagged as fake, tag and all. “They must’ve swapped it,” they say. I get the hope. But clinging to a dream while ignoring expert proof? That’s not passion—it’s delusion. And it’s how people lose real money.

Warning Signs & What NOT To Do:

<
• Don’t trust your eyes alone: Even seasoned dealers get fooled by today’s counterfeits. The 1943 copper cent is the most faked U.S. coin ever—and for good reason.

<

• Don’t assume the grading service messed up: It’s tempting to think PCGS or NGC “lost” your treasure. But their reputations depend on accuracy. Accusing them without proof only makes you look uninformed.

<

• Don’t fall in love before you verify: That “priceless” coin loses all value if it’s fake. Keep your heart out of it until the facts are clear.

Error Prevention & Recovery Strategies:

• Check for magnetism—fast: Real 1943 copper isn’t magnetic. If it sticks, it’s fake. This one test alone rules out 99% of fakes. Do it first.

<

• Get more than one expert opinion: Don’t rely on just one dealer. I send suspect 1943s to specialists like Andy at Angel Dees or Rick Snow. Different eyes catch different flaws.
• Bring learning tools: I keep printouts of counterfeit guides (like the one I handed out at Rosemont) to help collectors spot red flags—weight, plating flaws, die marks. Knowledge beats hype. print_educational_handout("1943_Copper_Diagnostics.pdf")
• Verify the grading tag: Make sure the PCGS/NGC tag isn’t tampered with. Match the coin’s weight and description. Cross-check the cert number online.
• Recovery: If you already bought a fake, contact the seller. Reputable dealers will fix the error. If not, document everything—photos, emails, tags. And remember: verify before you buy. That’s the real lesson.

2. Neglecting Pre-Show Logistics & Preparation

You wouldn’t hike the Rockies without boots. So why walk into Rosemont without a plan? I’ve seen dealers show up with tables half-set, collectors wandering like lost tourists, and everyone exhausted by noon. A little prep goes a long way—and saves a lot of stress.

Warning Signs & What NOT To Do:

• Don’t wait to book travel: Flights and hotels near the venue fill up fast. I got the Hyatt with the convention view—but only because I booked months out.
• Don’t show up without a plan: Four days is short. Wandering wastes time you can’t get back.
• Don’t forget the basics: Badge, cash, water, painkillers, business cards—missing one can ruin your day.

Error Prevention & Recovery Strategies:

• Book early—really early: As soon as 2026 dates drop, lock in flights and hotels. Use Google Flights price alerts. Connected hotels are worth the cost.
• Plan your day like a pro: Map out must-see dealers (e.g., the Indian cent guys), appointments, meals, and setup. I use a simple printed schedule—it works.
• Use this packing checklist:
  • Badge holder
  • Cash, cards, PayPal
  • Business cards (lots!)
  • Small bills for change
  • Water bottle (hydration = focus)
  • Phone + power bank
  • First-aid kit (ibuprofen, bandages)
  • Notebook & pen
  • Magnifier, gloves, loupe
  • Educational handouts
• Recovery: Forgot something? No shame. The bourse floor is full of helpful dealers—PCGS, ANACS, CAC, even your neighbors. Ask for a magnifier or a dollar bill. The coin community runs on trust and small favors.

3. Ignoring the Power of Networking & Relationships

This show isn’t just about coins. It’s about people. I met Larry Jewett (Coin World) over lunch, chatted with John Kent (ILNA President) about local events, admired Robert Julian’s stunning coin art, and shared a glass of wine with fellow dealers. These aren’t just conversations—they’re future deals, leads, and friendships. The real value in numismatics lives in relationships.

Warning Signs & What NOT To Do:

• Don’t hide behind your table (dealers) or just browse and bolt (collectors). The magic happens when you talk.

<

• Don’t eat alone: That lunch break is prime networking time.
• Don’t skip the follow-up: You had a great chat? Great. Now email them. Connect on LinkedIn. Send a note. That’s how connections become collaborators.

Error Prevention & Recovery Strategies:

• Schedule
