How to Submit Your Coins to Numex

Numex is only as good as the coins on the platform. If you're a serious collector, a dealer with inventory, or an estate holder with a collection to monetize, here's how to bring your coins into the Numex vault - and why it might be the smartest way to sell.

Who Should Submit

Numex accepts professionally graded coins from PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) - the two most trusted grading authorities in numismatics, with over 115 million coins certified between them.

If you have:

  • PCGS or NGC graded coins you want to sell without the hassle of individual listings
  • Dealer inventory you'd like to liquidate through a digital-native marketplace
  • An inherited collection you want to monetize transparently
  • Coins you're holding that could generate passive income through resale residuals

Then Numex is built for you.

Two Submission Paths

Path A: Graded Coins (PCGS or NGC Certified)

This is the fastest path. If your coin is already professionally graded and encapsulated in a PCGS or NGC holder (a "slab"), the process is streamlined:

  1. Enter your certification number on the Numex submission form. Our system verifies the cert directly against PCGS/NGC records - confirming the coin exists, its grade, denomination, year, and mint mark.

  2. Ship to the insured vault. Once your submission is approved, ship your coin through insured logistics to a Brinks-class secure vault facility. Numex provides shipping instructions and tracking.

  3. Vault acceptance and listing. After the vault confirms receipt and verifies the physical coin matches the certification record, your coin goes live on the Numex marketplace. It receives an onchain custody NFT, integrity proof, and product media.

  4. You earn lifetime curator residuals. As the original submitter - the "curator" - you earn a 1% residual on every future resale of that coin on the Numex marketplace, for as long as it stays in the vault. More on this below.

No upfront fees for graded coin submissions. You don't pay to list. Numex makes money when your coin sells.

Path B: Ungraded Coins

Have a coin you believe is valuable but it's not yet graded? Numex can help.

  1. Submit coin details and photos through the intake form. Include clear images of the obverse and reverse, any identifying marks, and your estimate of the coin's identity and condition.

  2. Numex reviews your submission. Our team evaluates whether the coin is a good candidate for professional grading and marketplace listing.

  3. Professional grading by PCGS or NGC. If accepted, your coin is sent to PCGS or NGC for official grading and encapsulation. The grading fee is charged upfront - the exact fee depends on the grading service, turnaround tier, and declared value. This cost will be clearly communicated before you commit.

  4. After grading, the coin enters the vault and is listed. From here, the flow is identical to graded submissions: vault custody, onchain registration, marketplace listing, and curator residuals.

The ungraded path takes longer (grading turnaround adds days to weeks), but it opens Numex to raw coins with strong potential. Professional grading also typically increases a coin's market value significantly.

The Curator Residual Model

This is the part that makes Numex submissions fundamentally different from selling on eBay, Heritage, or to a local dealer.

When you submit a coin to Numex, you become its original curator. As long as that coin remains in vault custody and trades on the Numex marketplace, you earn a 1% residual on every resale - not just the first sale, every subsequent one.

Here's how it works:

  • Rate: 1% of each resale price, deducted from the seller's proceeds (not the buyer's cost)
  • Duration: Lifetime, as long as the coin stays in vault custody
  • Stops: Permanently, if the coin is physically redeemed and leaves the vault
  • Payout: Residuals accrue in your account and are paid monthly when a minimum threshold ($25) is reached
  • Settlement: Handled through Stripe Connect - you'll complete a payout onboarding process

Example: You submit a 1921 Morgan Dollar graded MS-65. It sells for $500 on the marketplace. You earn $5. A year later, the new owner sells it for $600. You earn $6. Two years later, it sells again for $700. You earn $7. As long as that coin stays vaulted and trades, you keep earning.

This model is inspired by Courtyard.io, which pioneered curation rewards in vaulted trading card commerce. It works because it aligns incentives: submitters are rewarded for bringing quality inventory, and they benefit from the platform's growth over time.

Why Submit to Numex vs. Selling Elsewhere

Traditional selling channels take a big cut and offer nothing after the sale:

Channel Your Cost Ongoing Income Shipping Hassle
eBay ~13% final value fee + $0.30 None Every sale
Heritage Auctions Negotiable commission None Consignment
Whatnot 8–12% + processing fees None Every sale
Local dealer 5–15% below market (spread) None In person
Numex No upfront fee for graded coins 1% lifetime residuals Ship once to vault

With Numex, you ship your coin once - to the vault. After that, it trades digitally. No more packing, no more post office trips, no more shipping insurance anxiety. And every time it changes hands, you earn.

For a dealer with 100+ coins, the math compounds: each coin becomes a small but persistent income stream. For an estate holder, it means the collection keeps generating value long after the initial sale.
