CDX Auction — Timed Public Auctions, $0 FVF for SpotPro
List from SpotPro inventory or cdxauction.com. Collectors bid free. Winners pay you on Company Profile rails. SpotPro members always pay $0 to list and $0 platform final-value fee.
Why dealers leave money on other platforms
Major marketplaces train you to accept double-digit final value fees, forced checkout wallets, and listing friction that eats thin bullion margins. CDX Auction is built next to SpotPro: same stock, same photos, same payment methods buyers already use with your shop.
SpotPro members: $0 list · $0 platform FVF — always. Coin proceeds settle on your Authorize.Net, CARDZ3N, PayPal, Zelle, wire, or pickup rails. Public sellers (when allowlist opens wider) pay published marketplace rates; your SpotPro perk stays free on list and sell fees.

Three sales channels, one SpotPro stack
Stop running disconnected tools. SpotPro is the operating system; ExtraCoins, Coin Dealer X, and CDX Auction are the channels.
One inventory across retail, wholesale & auction
This is the advantage of running all three channels through SpotPro instead of separate eBay / Whatnot / spreadsheet stacks:
- POS is the source of truth — list the same SKU on ExtraCoins, Coin Dealer X, and CDX Auction without retyping titles and photos.
- Holds when it matters — first bid on a timed lot or a live-show queue reserves qty so the counter and web cannot double-sell that unit.
- ExtraCoins notices — product pages show when a piece is selling on cdxauction.com (live show or active bids) with a clear “get your bid in” path.
- Wholesale stays linked — Coin Dealer X checkout decrements the same POS quantity as floor and ExtraCoins sales.
- No-bid cleanup — if the last unit sells on the store or wholesale before anyone bids, open auction lots can end so you are not stuck with a ghost listing.
- One P&L story — paid web, wholesale, and auction activity land in SpotPro reports next to the cash register.

How valuable is SpotPro when auctions are free to sell?
The subscription is not a fee on each sale — it is the shop system that makes free auction selling possible without a second inventory stack:
- Greysheet-aware pricing and fair-value tools so you do not underbid yourself
- Unified qty so a counter sale and an auction bid do not double-sell the same coin
- Payment methods already configured for ExtraCoins apply to auction winners
- Live shows, SMS, Display Screen, and NumisNexus still run the rest of the business the same day

CDX Auction FAQ
-
What is CDX Auction?
CDX Auction (cdxauction.com) is SpotPro’s timed public auction marketplace for coins and bullion. Dealers list from SpotPro inventory or the auction site; collectors bid for free. Winners pay the selling dealer on that shop’s rails — not a platform escrow wallet.
-
How much do SpotPro members pay to list or sell on CDX Auction?
SpotPro members always pay $0 to list and $0 platform final-value fee (FVF). That is a membership perk, not a temporary beta discount. Public non-SpotPro seller plans (when open) use different rates — SpotPro shops stay $0 list / $0 FVF.
-
Can I list and manage auctions without opening SpotPro every time?
Yes. Linked sellers list from cdxauction.com/sell.php and manage live lots under Account → My listings — edit description, photos, QR phone capture, cancel at 0 bids, and relist. Deep POS inventory and shipping labels still live in SpotPro.
-
What are CDX Live Shows?
CDX Live Shows let you run a broadcast queue of lots (host desk + phone camera), then dump remaining pieces to timed floor auctions. Same stock pipeline as SpotPro — reserve qty, hammer, and post-show listings without retyping inventory.
-
How is CDX Auction different from Coin Dealer X wholesale?
Coin Dealer X (coindealerx.com) is vetted dealer-to-dealer fixed wholesale. CDX Auction is public timed bidding (and fixed-price catalog) for collectors and dealers. Both are SpotPro-connected channels with unified stock and $0 platform sell tax for SpotPro members on auction.
-
How does SpotPro keep ExtraCoins, wholesale, and auction inventory in sync?
SpotPro POS inventory is the source of truth. List the same SKU on ExtraCoins retail, Coin Dealer X wholesale, and CDX Auction. Qty holds on first bid or live-show queue; ExtraCoins product pages show “selling now on CDX Auction — get your bid in” when bids or a live show reserve the piece; counter, web, and wholesale sales cannot double-sell held stock. No-bid auction lots can end when the last unit sells elsewhere.
-
Do auction wins show in SpotPro reports?
Sold lots settle on your Company Profile payment methods. When you confirm payment and complete fulfillment, revenue is tracked in your SpotPro sales workflow so floor, ExtraCoins, CDX wholesale, and auction activity stay in one P&L story.
