Authenticate 1915 Coca-Cola Bottling Medals in Under 5 Minutes (3-Step Quick Verification)
December 9, 20253 Advanced Authentication Techniques for Vintage Coca-Cola Collectibles Experts Swear By
December 9, 2025I’ve Seen These Coca-Cola Medal Mistakes Destroy Collections – Here’s How to Avoid Them
After thirty years studying 1915 Pan Pac medals (the Jankovsky-740 brass facsimiles to collectors like us), I’ve watched good people lose thousands to the same avoidable errors. These medals have a wild history – English origins, Taiwanese knockoffs, shady dealers – that makes authentication a nightmare. Let me walk you through exactly where collectors trip up and how to protect your hard-earned collection.
Mistake 1: Ignoring the Weight Discrepancy
That Critical 1.1 Gram Difference
Here’s what most collectors miss: English originals weigh exactly 39.3 grams. Taiwanese fakes? They typically land at 38.2 grams. Don’t shrug this off – that tiny gap screams “fake!” Why?
- Chinese counterfeits use cheap zinc alloys under thin brass plating
- Weight variations reveal sloppy knockoff production
- Good digital scales cost less than dinner for two (under $25 on Amazon)
Do This Now: Weigh every medal candidate with calibrated jewelry scales. If it’s not between 39.2-39.4 grams? Walk away.
Mistake 2: Overlooking the CC Initials
The Microscopic Marker Even Experts Miss
On the reverse owl’s perch, original medals hide tiny “C.C” initials. Through my loupe, here’s what separates real from fake:
- Authentic: Crisp 0.3mm letters carved into the branch
- Fakes: Missing initials or smudged blobs
- This detail wasn’t public knowledge until recent collector forums

Mistake 3: Confusing Packaging Provenance
How Fake Boxes Trick Even Savvy Collectors
Original medals came in specific red boxes with gold lettering: “Drink Bottled Coca-Cola, Delicious and refreshing, Convention 1915 USA”. Spot fakes by their:
- Dull matte finish (originals were glossy)
- Wrong font weight on “Delicious”
- Flat borders without authentic embossing
Here’s the kicker – Taiwanese fakes never included boxes originally. Yet I’ve seen modern scammers pair fake medals with reproduction packaging. Always compare boxes side-by-side with verified examples.
Mistake 4: Falling for Associated Fantasy Items
The Tiffany Belt Buckle Scam That Still Snares Collectors
The same dealer behind these medals pushed fantasy “Tiffany” Coca-Cola belt buckles using familiar tricks:
- Phony letters claiming “records burned in a fire”
- Initial high-quality English-made batches
- Later Taiwanese copies with terrible craftsmanship

If You Bought One: Contact the American Numismatic Association’s Authentication Bureau before trying to resell – they’ve seen these before.
Mistake 5: Trusting Grading Company Labels Blindly
When Slabbed Medals Still Turn Out Fake
I’ve held “certified” medals in NGC/PCGS slabs that were obvious Taiwanese fakes. Protect yourself with this 3-step check:
- Verify certification numbers directly with the grading company
- Check for inconsistent descriptions (“Facsimile” vs “Fantasy” matters!)
- Demand close-up photos of edge reeding before buying
The smoking gun? Real English medals have 140-150 reeds – Taiwanese fakes always show 120-130.
Recovery Roadmap for Victims of Fraud
If you’ve bought a fake medal, don’t panic:
- Document Everything: Snap detailed photos of markings, weight readings, and packaging
- Act Fast: Contact eBay/PayPal immediately – their fraud protection windows close fast
- Report It: File with the Internet Crime Complaint Center (IC3) – they track collectible scams
Your Defense Against Coca-Cola Medal Scams
Getting these five details down cold – weight tolerances, hidden initials, box quality, manufacturer history, and slab verification – will save you from most Jankovsky-740 scams. Remember: that rush of finding a “rare” medal clouds judgment. Keep your scale handy, your loupe closer, and happy collecting!
