Card Catchers Protection Standard
How the Sandwich Protocol protects serious trades
Card Catchers was built for collectors who care about condition, trust, and protection. For qualifying trades, the Sandwich Protocol adds a stricter packing standard so high-value cards are secured between two rigid protectors before they move.
- Applies to trades with a combined estimated value of $30 or more, or any individual card valued at $15 or more.
- The sleeved card is secured between two rigid toploaders or hard cases to help protect against bending, warping, and shipping pressure.
- Qualifying trades are manually reviewed and verified by the owner before being posted or finalized.

Protection built for valuable cards
Made for serious collectors
Protocol Trigger
$30+ trade total
Also applies when a single card in the trade is valued at $15 or more.
How It Works
From trade post to protected delivery, every qualifying trade follows a tighter process
The Sandwich Protocol is not a separate service added at the end. It is part of how Card Catchers handles qualifying trades so protection and verification are built into the workflow from the start.
02
Manual review and verification
Qualifying trades are manually reviewed by the owner before they are posted or finalized. That added check helps keep the process tighter when the stakes are higher.

Protected under the Sandwich Protocol
If the trade meets the value threshold, the sleeved card is secured between two rigid toploaders or hard cases to help reduce risk during handling and shipping.
Sleeved first
Rigid protection on both sides
When it applies
The Sandwich Protocol applies to any trade with a combined estimated value of $30 or more, or any individual card valued at $15 or more.
What it means
The card is sleeved and then protected between two rigid toploaders or hard cases. The goal is straightforward: add structure around the card where shipping pressure usually does damage.
Why collectors care
Valuable cards are condition-sensitive. Adding reinforced protection helps reduce the risk of bending, warping, and avoidable pressure damage while the trade is in motion.
Protection Stack
The structure is simple because simple is dependable
The Sandwich Protocol is named after the way the card is protected. The sleeve keeps the card clean and controlled, while rigid protection on both sides helps resist the kinds of pressure that can compromise condition.
Sleeve first
The card is sleeved before it is secured inside the protocol.
Rigid support on both sides
Two rigid toploaders or hard cases create structure around the card instead of leaving one side exposed.
Built for valuable trades
The threshold is designed around the trades where condition protection matters most.
Why It Matters
More protection where condition risk gets expensive
Higher-value cards deserve tighter handling standards. The Sandwich Protocol gives qualifying trades extra structure without adding noise to the process.
Built for condition-conscious collectors
When the value climbs, even minor damage matters more. This protocol is designed around that reality.
Matches the Card Catchers review process
Manual review by the owner helps support a tighter workflow for trades that meet the protection threshold.
Clear standard, not guesswork
The value thresholds are defined up front, so qualifying trades are easy to understand before they move.
Focused on real shipping risk
Rigid protection on both sides helps address pressure and flex that can affect a card during transit.
Quick Answers
What collectors usually want to know first
These are the key details behind the protocol. If your trade meets the threshold, the protection standard is part of the process, not an optional extra.
$30+
Combined estimated trade value that triggers the Sandwich Protocol.
$15+
Single-card value that also triggers the protocol even if the full trade total is lower.
What exactly activates the Sandwich Protocol?
It applies when the combined estimated value of the trade is $30 or more, or when any single card in the trade is valued at $15 or more.
What protection does the protocol add?
The sleeved card is secured between two rigid toploaders or hard cases. That added structure is intended to help protect against bending, warping, and shipping pressure.
Is there a verification step for qualifying trades?
Yes. Qualifying trades are manually reviewed and verified by the owner before they are posted or finalized.
Is the Sandwich Protocol only for very expensive cards?
No. It was built to cover more than just ultra-high-end trades. A single card valued at $15 or more can qualify, even if the full trade total is below $30.
Ready To Trade
Trade with a protection standard that actually respects the card
Post your trade, connect with other collectors, and know that qualifying cards are handled under the Sandwich Protocol when the value calls for it.
Card Catchers currently routes qualifying trades through manual owner review and verification. Sandwich Protocol thresholds: $30+ combined trade value or $15+ on any individual card.
