Can I tag posts by coin series, die variety, and grade on VeloCMS?
Yes. VeloCMS's graded-slab inventory post type includes dedicated fields for series (Lincoln cent, Morgan dollar, ancient Greek, Roman Imperial, and all standard series — plus custom series tags for specialized areas), date and mintmark, PCGS/NGC grade in full Sheldon-scale notation including all grade modifiers (MS-65+, PR-69 DCAM, CAC sticker status), FS- variety attribution for die varieties, VAM number for Morgan and Peace dollars, and corpus reference for ancient coins. Each field is structured for JSON-LD output — so when a collector searches 'MS-65 Buffalo Nickel die variety registry' on Perplexity or ChatGPT Search, your archive surfaces rather than a PCGS forum thread.
Does VeloCMS support PCGS/NGC cert lookup integration?
Yes. The graded-slab inventory post type includes a cert number field with a verified external link to the PCGS or NGC cert verification database — so readers can confirm the grade, the variety attribution, and the certification status directly from your post without leaving the page. The cert link is structured as a canonical reference in the JSON-LD output, connecting your numismatic analysis to the grading service's official verification record.
How does ancient coin provenance chain documentation work?
The ancient coin provenance archive post type includes a full sale/auction record chain: each auction house that has sold the piece (ANE, NAC, CNG, Roma, Heritage — with catalog number, lot number, sale date, and realized price), each dealer who has offered it, and each major collection in whose cabinet it resided (using standard pedigree abbreviations like 'ex Fontana Collection' or 'ex Norweb Collection'). The die-linkage analysis field documents which obverse or reverse die the coin shares with other known examples in the relevant corpus. Multi-image documentation supports standard face shots plus patina detail shots and edge documentation for the condition assessment that ancient coin collecting requires.
Can I build a die-variety registry with FS- attributions and VAM documentation?
Yes. The die-variety registry post type includes the FS- variety number from the Cherrypickers' Guide (or VAM number for Morgan and Peace dollars), a die-marriage attribution table documenting the identifying characteristics of both the obverse and reverse dies, die-state progression photographs showing the variety across its die life, a photo overlay comparison tool rendering the variety die against a normal example at identical zoom levels with opacity control, and population context from PCGS and NGC attribution records. The member-only die-marriage atlas reserves highest-resolution die-state photography for subscribed readers.
How does the member-only die-marriage atlas work?
The member-only die-marriage atlas lets you publish die-variety documentation at two tiers — a public post with the variety attribution, the die-marriage description, and representative photographs that are accessible to all readers, and a member-only tier with the highest-resolution die-state photography, the complete attribution methodology (the argument for why this die marriage is distinct from similar varieties, the die diagnostic that is definitive rather than suggestive), and early notification of new variety discoveries before they go public. Subscribers receive email notifications when a new member-only die-marriage is published. BYOK Stripe means subscription revenue goes directly to your account at 0% platform fee.
Does VeloCMS support mint-error photo overlay for off-center strikes and planchet errors?
Yes. The mint-error documentation post type includes a photo overlay comparison tool that renders two photographs at identical zoom levels with opacity control — the error coin and a normal example — for visual confirmation that a doubled die's separation is genuine hub doubling rather than machine doubling, that an off-center strike's percentage is accurately estimated, or that a planchet error's characteristics match the claimed error type. The structured error-type taxonomy (doubled die by class, repunched mintmark, off-center strike with percentage, clipped planchet, wrong-planchet error, die cap, brockage) makes each mint-error post findable by the specific error type.
Can I embed Greysheet CDN valuation context in my graded-slab posts?
Yes. The graded-slab inventory post type includes a Greysheet/CDN valuation context field where you can document the current CDN bid price, CDN ask price, and CPG retail value for the specific date, mintmark, and grade combination — the three pricing reference points that serious buyers and sellers use in the primary dealer market. The valuation context is dated so readers know when the pricing data was collected, and the format supports your analytical narrative explaining where the coin trades in practice relative to the sheet prices.
What theme works best for a numismatic archive or die-variety registry?
Atelier Modern — refined editorial typography, high-resolution specimen photography support, and a clean visual presentation that matches the register of quality numismatic auction catalog design — is the primary recommendation for graded-slab inventory publishers, ancient coin provenance archivists, and die-variety registry builders. It renders obverse/reverse coin photography in the visual context that serious collectors expect from a credible numismatic publication. For variety researchers who prefer a more scholarly presentation with footnote support and catalog-depth typography, Memo Garamond (EB Garamond body text, academic aesthetic, citation-friendly) is a strong alternative. Both themes are free on all plans. See the full gallery at /themes.
