Submitting a Rare Coin for Certification: What You Need to Know
So you’ve inherited or discovered a rare coin. It looks valuable, maybe
even historic, and your first instinct might be to drive it to a grading
company for an appointment. Stop right there. Coin certification doesn’t
work like a local appraisal shop. The major grading services PCGS, NGC, and CAC operate secure laboratories with no public
walk‑ins, no appointments, and no “drop‑off” service. Every coin must be
submitted through the proper channels.
This guide explains exactly how to submit your coin for certification,
covering the do’s and don’ts, where to find submission forms, how to pack and
ship coins safely, and what to expect with insurance and postal service
protocols.
Step 1: Know the Certification
Companies & Addresses
- PCGS (Professional Coin Grading
Service)
- The
mail address for PCGS submissions
via USPS is P.O.
Box 9458, Newport Beach, CA. For FedEx express shipments, use the
address 1610
E. St. Andrew Place, Suite 150, Santa Ana, CA 92705
- NGC (Numismatic Guaranty Company)
- 5501 Communications Parkway,
Sarasota, FL 34240
- CAC Grading

Edgewater, NJ 07020
Step 2: Download Submission Forms
- PCGS Forms: PCGS Submission Forms
- NGC Forms: NGC Submission Instructions
- CAC Forms: CAC Grading Submission Portal
You’ll need to be a member or work through an authorized dealer to submit
directly.
Step 3: Pack Your Coin Correctly
- Place each coin in a 2.5"
x 2.5" Mylar flip (never tape or staple).
- Label flips with submission
numbers.
- Cushion with bubble wrap or
styrofoam, secure with rubber bands.
- Use a new, sturdy box
sealed with reinforced paper tape (required for USPS Registered Mail).
- Include your completed submission
form inside.
Step 4: Ship Securely
- USPS Registered Mail is the most secure option.
- Request Certified Mail with
Return Receipt for proof of delivery.
- PCGS and NGC recommend USPS
Registered Mail for high‑value coins; FedEx is also accepted.
- Expect slower delivery with
Registered Mail due to its lock‑and‑key handling.
Step 5: Insure Properly
- Insure for the declared value
(your estimate of the coin’s worth).
- USPS Registered Mail allows
insurance up to $50,000 per package.
- PCGS and NGC provide additional
insurance for return shipments (up to $100,000).
Step 6: Understand Postal Service
Protocols
- Packages are sealed with paper
tape to prevent tampering.
- Every transfer requires a
signature, making Registered Mail highly secure.
- No, the postal service does not
photograph your coin. They only track the package externally.
- The “red flag” is simply that
Registered Mail is slower because of its security measures.
Conclusion
Submitting a coin for certification isn’t complicated, but it requires
precision. No walk‑ins, no appointments, no shortcuts. By using official
forms, packing carefully, and shipping securely with insurance, you protect
both your coin and its future value. Certification transforms a coin from
“interesting” to “market‑ready,” giving you peace of mind whether you keep it
as a family treasure or sell it to a collector.
