CX CDX Auction Docs
Feature overview

What’s live on CDX Auction

One place that lists current product capabilities in everyday language. Marketing pitch: Why CDX. Word definitions: word list.

1. Core marketplace

Timed auctions

Lots have a start and end time. You set a max bid. Activity near the end can add time to the clock.

Buy Now & fixed price

Optional Buy Now on auctions. Fixed-price lots with no bidding. On bullion, Buy Now can update when metal prices move.

Make offer

Private best offer when the seller allows it. Accept, counter, or decline. Not a public bid.

No buyer premium

CDX does not add a percentage on top of the sold price for buyers (unlike many major houses).

Ending soon

Dedicated view of lots closing soon, with heat / urgency sorting. /ending.php

Shop TV view

Full-screen focus on the next ending lot — useful for a shop TV. Timed auctions, not a live show fee product. /theater.php

Lots with video

Product video on the lot page and Prime lane. /prime.php

Dealer stores

Public storefronts with about, policies, feedback, live / fixed / sold. /sellers.php

2. Value tools

Metal value

Live metal price × weight × purity on bullion cards. Coin shops sometimes call this “melt” — we say metal value.

Great deals

Lots scored great / fair / premium vs metal, wholesale guides, and retail averages. Filter: ?filter=deals

Below metal value

Browse lots asking less than raw metal. Filter

Guide price chips

Saved dollars from the shop’s inventory when guide pricing is linked. Not looked up live on every page view.

Live metal markets board

Gold, silver, platinum, palladium prices on the home page. Bullion Buy Now can follow these prices.
