No double-selling
Putting a coin on auction does not lock it by itself. Once someone bids — or you put it in a live show — that piece is held so the counter and website cannot sell it again.
Website. Wholesale. Auction. Same stock.
You should not have to keep three different lists. SpotPro uses one count for the case, the website, other dealers, and the auction floor.
| Where | Website | Who buys | How it prices | SpotPro fees |
|---|---|---|---|---|
| ExtraCoins | yourname.extracoins.com | Collectors / public | Fixed retail (bullion can follow spot) | $0 list / $0 sell commission from SpotPro |
| Coin Dealer X | coindealerx.com | Other dealers (vetted) | Fixed wholesale | Included for eligible members — no SpotPro GMV take |
| CDX Auction | cdxauction.com | Public and dealers | Bidding and live shows | Members: $0 list / $0 platform FVF; buyer pays you |
Website notices
If a piece is live on auction, the ExtraCoins product page can say so and point people to bid instead of buying fixed price.
Sold out elsewhere
If the last one sells in the store or wholesale before any bid, open auctions with no bids can close so you are not stuck with a dead listing.
Money comes to you
Buyers pay your shop — card, Zelle, wire, pickup, and the methods you already use. We are not holding the buyer’s money as a middleman wallet.
