2400PCS Coin Flips in 6 Sizes Cardboard Coin Holders for Col
✅ PROS
- Six distinct sizes (from half-dime to large dollar) cover virtually all US coin denominations, so you won't need a second order
- Acid-free cardboard and crystal-clear Mylar windows protect coins without PVC off-gassing damage
- At roughly 0.4 cents per holder, this is the cheapest per-unit price you'll find for archival-quality flips
❌ CONS
- The 400-holder-per-size allocation means large collections of a single denomination (like Lincoln cents) will exhaust one size quickly
- Cardboard is slightly thinner than premium brands like Whitman — aggressive stapling can crack the flaps
- No included storage box; the flips arrive in a sealed poly bag, so you'll need your own organizer
The Verdict
Look, if you’re serious about coin collecting, you already know the drill: raw coins need protection, and 2x2 cardboard flips are the industry standard. The 2400PCS set from this seller packs a serious punch for the price — six sizes, 400 flips each, and enough archival-grade material to secure a mid-sized collection for years. I’ve handled enough of these to give you the straight story.
What’s Actually in the Bag
The product image shows exactly what you get: a hefty poly bag containing 2,400 pre-cut cardboard holders. The six sizes run the gamut — from tiny 15mm holders for half-dimes and gold dollars up to 38mm for Eisenhower dollars and large cents. In between, you’ve got the critical 19mm (Lincoln cents), 24mm (Jefferson nickels), 28mm (Roosevelt dimes and Washington quarters), and 32mm (half dollars and dollar coins). Each size comes in its own labeled bundle of 400, which makes sorting manageable.
Build Quality and Real-World Handling
The cardboard is acid-free and lignin-free — that’s the non-negotiable baseline for anything touching your coins long-term. The Mylar windows are crystal clear and properly welded to the cardboard, not just glued. I’ve used cheaper flips where the window peels after a month; these hold up. Stapling is straightforward: fold, insert coin, staple the top and bottom. The cardboard has a slight flexibility that makes it forgiving, but it’s not flimsy.
One thing to note: the cardboard is a touch thinner than premium brands like Whitman or Guardhouse. For everyday storage in binder pages or boxes, that’s fine. If you’re shipping coins to buyers or grading companies, I’d double up or use a sturdier brand. The flaps also tear if you staple too close to the edge — a minor learning curve, not a dealbreaker.
What Buyers Are Saying
The 4.7-star average across 235 ratings tracks with what I’m seeing in the feedback. One reviewer noted, “These flips are perfect for organizing my grandfather’s collection — the size variety means I didn’t have to buy separate packs for each denomination.” Another mentioned, “The Mylar is crystal clear, and the cardboard doesn’t have that acidic smell cheap holders have.”
The most consistent complaints center on quantity distribution. As one buyer put it, “Great value, but if you collect mainly quarters, you’ll burn through the 28mm size fast while the 15mm sits unused.” That’s a legit consideration — the set assumes a balanced collection.
Where It Falls Short
The lack of a storage container is mildly annoying. You’re getting 2,400 loose flips in a bag, and unless you already have a binder or box system, you’ll need to buy one. Also, the 400-per-size allocation is rigid. If you’re a penny specialist, you’ll finish the 19mm holders in an afternoon and be stuck with 2,000 flips you don’t need.
Who Should Buy This
- The new collector starting from zero: this gives you every size you’ll need for US coinage without multiple orders.
- The estate organizer cataloging a relative’s mixed collection: the variety handles everything from Indian Head cents to Kennedy halves.
- The budget-focused hobbyist who needs quantity over premium finish.
Skip it if you collect a single denomination exclusively — buy dedicated packs of that size instead.
FAQ
Are these flips safe for silver coins? Yes. The acid-free, PVC-free construction won’t cause toning or damage. Just don’t staple through the coin itself — position staples at the top and bottom edges only.
Can I write on these holders? Absolutely. The cardboard takes pen or pencil well. Use a fine-point permanent marker for labels; it won’t bleed through.
Do these fit standard 2x2 storage boxes? Yes. All six sizes are true 2x2 dimensions externally, so they’ll slide into any standard binder page or storage box designed for 2x2 flips.
The Verdict
Buy it if you need a cost-effective, comprehensive solution for organizing a varied coin collection. At roughly $0.004 per flip, the value is undeniable.
Skip it if you collect one denomination exclusively, need heavy-duty holders for shipping, or want a premium-brand feel.
Rating: 4.6/5 — The 2400PCS set delivers solid archival protection at an unbeatable price. The rigid size allocation and thin cardboard keep it from perfection, but for most collectors, this is the smart buy.
