NM/VG+ is not “Used”

A second-hand record is not adequately described by “Used”. The pressing matters, the physical copy matters, and the media and sleeve can have different conditions.

That is obvious to a record seller. It becomes less obvious when a listing moves between systems built for general retail. Two precise grades can enter an integration and emerge as one broad condition. The listing still exists, but part of the product has disappeared from the data.

The frustration is not really about wording. It is about a workflow that makes a seller re-enter information they have already reviewed. Good software should reduce that work without replacing useful detail with a guess.

Two grades describe one physical copy

A record’s media and its sleeve are assessed separately. NM/VG+ means the media is Near Mint and the sleeve is Very Good Plus. VG+/NM describes a different copy. Reversing those values changes what the buyer is being offered, even though the artist, title and pressing remain the same.

Discogs uses the Goldmine Standard for Marketplace grading. Its vocabulary runs from Mint through Near Mint, Very Good Plus and lower grades, with special sleeve states such as Generic. A generic sleeve is not simply an ungraded original sleeve; it is a different fact about what accompanies the media.

That gives a record listing at least three distinct layers:

These layers are related, but none is a substitute for another. A Release ID identifies a catalogue record, not the condition of the copy in a seller’s hand. A Listing ID identifies an offer, not the Stock item’s permanent identity. The Stock item connects the reviewed physical copy to the listings that offer it.

Condition is commercial data

Grading is not decorative catalogue copy. It helps explain the price and sets the buyer’s expectation before an order is placed. Discogs’ grading guidance even describes broad value relationships between several grades and a Near Mint reference value. Flattening those grades to “Used” removes part of the evidence behind the offer.

The operational risk runs in both directions. An overstated grade can cause a return, refund or dispute. An understated grade can make a good copy look ordinary and weaken the seller’s price. A free-text note helps a buyer, but it does not replace controlled, separately stored condition facts.

What gets lost between Channels

General-purpose commerce systems often have a broad item condition because they need to describe everything from books to electronics. Record grading is more specific. The safe response is not to force every destination into the same shape; it is to preserve the source facts and map them only where the destination has a suitable contract.

On eBay, descriptive aspects belong to a marketplace’s current leaf-category contract. The eBay Taxonomy guidance explains that category trees differ between marketplaces and can change, while each category defines its own required or optional aspects and allowed values. An integration therefore needs to read the current contract for the chosen marketplace and category rather than hard-code one universal record-grading table.

Shopify takes a different approach. Metafields provide typed custom data when the standard product model does not contain a suitable field. That can preserve media and sleeve grades as structured facts, while the storefront theme decides how buyers see them.

Where a destination provides no equivalent structured field, the grades should still remain in the source-of-truth record and appear in buyer-visible listing copy where appropriate. Unsupported does not have to mean discarded.

A safe mapping is explicit

Record condition should pass through a controlled mapping, not a chain of assumptions. A dependable workflow should:

• store media condition and sleeve condition separately;
• retain the original reviewed values and their source;
• normalise only through a documented condition vocabulary;
• use the destination’s current category and field constraints;
• preserve exceptional states such as Generic or No Cover;
• surface unsupported or ambiguous values for review; and
• never overwrite a reviewed physical-copy fact silently.

A broad “Used” condition may still be required by a Channel. It can coexist with more precise record grades. The mistake is treating that broad value as though it contains the same information.

Pressing identity has the same problem

Artist and title do not uniquely identify a record. Country, year, label, catalogue number, format and manufacturing details can distinguish one release from another. Those differences can matter to collectors and to the seller’s price.

The catalogue identity should therefore remain evidence attached to the product, while the condition belongs to the physical Stock item. If both are flattened into a generic product title, a later import cannot safely tell which pressing or copy it has found.

This is the same distinction explored in When a catalogue count is not a stock count: a catalogue record tells you what identity exists; it does not, on its own, prove which physical unit is present or sellable.

What ChannelWeave does today

ChannelWeave’s Discogs tools keep the provider’s catalogue identity separate from local Stock and Listings. Media Condition and Sleeve Condition remain separate reviewed Reference facts on the physical Stock item.

When a current Discogs listing is imported from a manually downloaded CSV, ChannelWeave asks the operator to match it to one physical Stock item. Imported grades are shown beside the Stock grades, and missing Stock grades can be filled only through an explicit, non-overwriting review action. Historical Sold rows do not create Stock, Listings or Sales.

Catalogue enrichment follows the same boundary. A Discogs Release ID can support the identity of a release, but it does not become the Stock primary key and it does not confirm the condition of the seller’s copy. The Discogs guide explains the current file-based workflow and its limits.

This does not pretend that every Channel has the same grading model. It establishes the safer foundation: preserve the facts first, then make each destination mapping explicit and reviewable.

Final thought

Pressing identity tells you which record it is. Media and sleeve condition tell you what this copy is like. The listing tells you where and how it is offered.

Good multichannel software keeps all three meanings intact. NM/VG+ is not “Used”; it is useful, structured evidence about the thing the buyer is actually buying.
