Adult-signature delivery is usually not worth buying solely to protect an expensive Pokémon slab, because it verifies the recipient's age rather than insuring the card. Pay for it when you need age or addressee control; otherwise, prioritize adequate coverage, secure packing, and an appropriate signature service. A slab is a graded card sealed in a rigid holder. For these collectibles, signature service reduces unattended-delivery risk, but reimbursement depends on separate insurance or declared-value terms.

What adult signature actually provides
USPS Adult signature Required demands a signature from someone age 21 or older at the address, with photo identification. Adult Signature Restricted Delivery is narrower because only the named addressee may accept the parcel, according to the USPS adult-signature guidance. That control can matter when nobody else should receive the slab.
It does not establish the card's value, add loss or damage coverage, or accelerate delivery. For most card sales, the practical question is not whether the recipient is 21. It is whether the package receives a documented handoff and whether the sender can recover the slab's supported value if something goes wrong.
The USPS cost comparison
USPS currently charges $9.70 for Adult Signature Required and $10.00 for Adult Signature Restricted Delivery, in addition to postage. The service must be selected when postage is purchased and is unavailable at retail counters. Insurance is a separate expense.
USPS domestic insurance covers up to $5,000 and costs $9.05 plus $1.50 for each $100, or fraction thereof, above $600, under the USPS Notice 123 price list. For a $1,000 slab, the comparison before postage is: Spending $9.70 only on adult signature leaves the slab without additional loss or damage coverage. If the budget forces a choice, that distinction usually makes insurance the more relevant protection against financial loss.
- $15.05 for $1,000 of USPS insurance
- $9.70 for Adult Signature Required without added coverage
- $24.75 for both $1,000 of insurance and Adult Signature Required
- $25.05 for $1,000 of insurance and Restricted Delivery
How FedEx handles high-value packages
FedEx automatically applies Direct Signature Required to U.S. and Canadian packages with a declared value of at least $500. Someone at the delivery address must sign, but that person need not be the addressee or an adult; FedEx charges no separate direct-signature fee on those packages. Adult Signature Required is the stricter age-21-and-identification option.
It adds recipient-age control, not a stronger stated right to reimbursement. FedEx also warns that declared value is not insurance. A claim requires proof of loss or damage and FedEx fault, while payment cannot exceed the lesser of repair cost, depreciated value, or replacement cost, as explained in the FedEx declared-value terms. A high declared value and a signature therefore do not replace careful packing or a separate coverage decision.
Match the service to the slab
Choose services by the actual risk instead of treating "adult signature" as a synonym for "high-value protection." For a slab above USPS's $5,000 domestic insurance limit, Registered Mail permits insurance up to $50,000. Its declared-value fee is $40.50 for $4,000 through $5,000, then $3.10 for each additional $1,000, plus postage.
- For a slab below $500, compare ordinary signature options with the cost of appropriate coverage.
- At $500 or more through FedEx, account for the automatic Direct Signature Required service before paying for stricter age verification.
- Use USPS Adult Signature Required when any eligible adult resident may accept the package.
- Use USPS Restricted Delivery when only the named addressee should receive it.
- Buy loss or damage coverage separately; signature service alone does not supply it.
Shipping slabs to PSA
The risk allocation changes when a collector sends cards to a grading company. PSA states that the sender carries the cost and risk of inbound transit until PSA has unpacked the shipment and confirmed receipt. PSA generally returns completed submissions through a third-party carrier with signature required, according to its May 2026 terms and conditions.
That return signature does not protect the collector's outbound shipment to PSA. Before sending an expensive slab or submission, select coverage for the full supportable value, pack it correctly, and retain the shipment and value documentation. For inbound PSA shipments, the sender remains responsible until PSA confirms receipt after unpacking.
