CX CDX Auction

Seller fee comparison

What other sites take — and what you keep on CDX

Built for coin & bullion dealers: metal-value badges, wholesale guide prices, SpotPro barcodes, local pickup QR, and $0 platform list/sell for SpotPro sellers — always. Buyers pay you — CDX is not holding your coin proceeds in a marketplace wallet. Glossary

Whatnot pain

  • Live-show chaos: FOMO bids, no quiet research
  • Seller commission + processing on every show
  • Hard to run melt-aware max proxies while hosting
  • Inventory lives in the show — not your POS barcode

Timed live floor — no live-show fee

CDX advantage

  • $0 list / $0 platform sell (beta) — keep the metal premium
  • Melt, Greysheet, retail fair-value on every bullion lot
  • POS hold only after first bid — counter stays open
  • Timed theater + TV mode without show-night tax
  • Winners pay you on Company Profile processors
  • Description writer + bullion subtype tools from SpotPro entry

From live shows to CDX timed auctions

Live energy, shop discipline
Open TV / watch-party floor view on the lobby screen. Auto-advance ending lots. No commission on every “sold!”.
Metal-value bidding
Buyers can set a max as a % of metal value, with verified accounts. No mid-show shipping chaos.
SpotPro Software is the source of truth
List from SpotPro Software or CDX sell with bullion subtypes. Barcode + media stay where your staff already work.
Leave the show fee behind
Same social proof, better economics: estate batch, CSV import, wholesale packs, dealer swap board.

Annualized spite (for the spreadsheet people)

If you average 20 lots/month at $500 each (~$120,000/yr GMV): eBay model ~$15,900/yr in fees · Whatnot model ~$14,280/yr · CDX platform ~$0. That is not a promo code — it is the product.
