Listing Methodology

Show listings

Coin show listings on US Coin Shows come from three sources:

1. Organizer submissions — Show organizers create and manage listings directly through our platform. These listings are marked as Submitted by Organizer after editorial review.
2. Public-source research — Our editorial team and automated tools research show listings from public directories, club websites, and official organizer pages. These are marked as Imported Listing until verified.
3. Direct verification — When we contact an organizer to confirm dates, venue, and details, the listing is upgraded to Verified with Organizer status.

All show pages display their current listing status and, where available, the date details were last verified. Travel-sensitive information such as dates and venue details can change; always confirm with the organizer before attending.

Dealer listings

Dealer directory entries on US Coin Shows come from four sources:

1. Dealer-claimed profiles — Coin dealers register and claim their profile directly, providing current contact information, specialties, show attendance, and business details.
2. Editorial research — Our team builds profiles from public business information, including address records, website content, and numismatic directory data.
3. Enrichment services — Where available, we supplement profiles with publicly available business data including hours, ratings, and business classification.
4. Direct verification — When we confirm a dealer's location, contact, or membership details directly, those fields are marked as verified.

Unclaimed profiles are marked as Imported Listing. The business owner can claim the profile at any time to take control of their listing.

Data freshness

Where available, each listing page displays one of the following timestamps:

• Last verified — for directory facts confirmed by direct contact or review
• Last reviewed — for editorial learning content checked by our team
• Last updated — for general page or listing revisions

Corrections

We welcome corrections from organizers, dealers, and collectors. If you see an inaccurate date, venue, business detail, or summary, please report it with a supporting source.

Why methodology matters in a numismatic directory

Coin show information has traditionally been fragmented across club newsletters, regional association websites, and informal word-of-mouth networks. No single directory has ever aggregated it comprehensively. The result has been that collectors and dealers often miss shows entirely, or arrive to find dates or venues have changed without notice.

US Coin Shows was built to solve this problem. Our methodology reflects the reality that building a trustworthy directory requires more than a one-time data collection effort. It requires ongoing maintenance, direct relationships with organizers, tools that let dealers keep their own information current, and a clear system for communicating how confident we are in each piece of data. The provenance status displayed on every show and dealer page is our commitment to transparency about what we know, how we know it, and when we last checked.

We believe collectors deserve to know not just what a listing says, but how reliable that information is likely to be. A show submitted by the organizer directly, with dates confirmed by our team, is fundamentally different from a show assembled from a club calendar that was last updated two years ago. Our methodology makes that difference visible.
