Can a collector sue a grader for negligent grading that caused financial loss?

The duty of care — does a grader owe one to the note's owner?

A professional grading service accepts a note for grading, charges a fee, and issues a certified grade that the owner will rely on in commercial transactions. This relationship — paid professional service, known reliance, specific expert output — is sufficient to establish a duty of care. The grader who grades a note negligently owes a duty to the person who submitted the note and paid for the service. Whether that duty extends to subsequent buyers of the graded note is less clear — it depends on whether the subsequent buyer relied on the grade in a way that the grader could reasonably have foreseen.

The standard of care — what constitutes negligent grading

Negligent grading means: applying a grade that no competent professional grader, exercising ordinary professional skill and care, would have applied to the note. The standard is not perfection — grading involves judgment, and reasonable professionals can disagree by one or two grade points. But a note graded MS-65 that any competent numismatist would grade VF-25 is a negligent departure from professional standards. The claimant needs an expert witness who can testify that the grade was outside the range of reasonable professional judgment.

TPG terms and conditions — the liability limitation

PMG, PCGS, and NGC all have detailed terms and conditions that: limit their liability to the fee charged for the grading service; disclaim liability for consequential losses; and provide dispute resolution procedures (typically re-grading by the same service). These terms are presented to submitters when the note is submitted. A submitter who accepted the terms has contractually limited their remedies against the grader to what the terms permit.

Indian courts may examine whether these liability limitation terms are enforceable under the Consumer Protection Act 2019 (which limits the effectiveness of unfair contract terms in consumer transactions) or whether they were sufficiently brought to the submitter's attention before submission. But the reality is that grade disputes between collectors and TPG services are very rarely litigated — the industry norm is to seek re-grading, not litigation.

The consumer forum as the practical route

A collector who believes PMG graded their note negligently and sold it for less than it was worth as a result has a consumer forum complaint for deficiency of service — the grading service did not perform its professional service with reasonable skill and care. The consumer forum can award: compensation for the loss of value caused by the wrong grade; the cost of re-grading; and costs of the proceedings. This is more practical than a full civil suit and does not require navigating the TPG's liability limitation terms in a superior court.
