Member trading

Exchange and auction terms

Rules for member listings, transactions, moderation, responsibility and the current limits of the service.

Last updated: 17 October 2026

Eligibility and accounts

Members must provide accurate information and protect their accounts. Only approved trading members may submit exchange or auction listings. Approval is not TAMRA certification of a person's identity, credit, goods or every transaction. Accounts must not be transferred, impersonated or used to evade suspension.

Seller responsibilities

A seller must have the right to sell the listed object, use clear recent photographs of that object, accurately describe its name, price, condition, repairs, damage, measurements and known provenance, and retain proof of dispatch and handover. Stolen goods, counterfeits represented as genuine, legally restricted cultural property, infringing goods, weapons, drugs and other prohibited items must not be listed.

Buyer responsibility and authenticity

Buyers should read the full disclosure, ask about uncertainties and arrange in-hand inspection or an independent second opinion where value warrants it. Articles, votes, comments, publication approval, certificate images and AI translations are not TAMRA guarantees of authenticity, value, age or efficacy. Sellers remain responsible to their transaction counterparty for their specific representations.

Reservations, messages and cancellation

Selecting “I want this” or becoming the highest bidder creates a transaction record and site conversation; it does not mean TAMRA has received money or guarantees completion. The parties must confirm the object, amount, currency, delivery fee, payment method, dispatch deadline, inspection and return conditions in site messages. A delayed reply does not permit either party to publish private information or harass the other.

Moderation and enforcement

TAMRA may request more information, refuse or remove content, preserve transaction records, restrict features or suspend an account to address rule breaches, risk, fraud, or requirements from courts and authorities. Moderation maintains basic information and safety standards; it does not replace professional authentication, legal advice or transaction due diligence.
