COLLECTORIUM
About memberships, public negotiation, proposal privacy and service boundaries.
No. Verified Free accounts can start offers on up to 6 different listings per UTC calendar month across public and private negotiation. Revising an offer uses no monthly allowance, even across months. A listing counts only once in a month, including after withdrawal, decline, closure, reactivation or a new acquisition; used allowance is not restored. Pro and Premium members can have offers active on up to 20 different listings at a time, with no monthly submission quota. There is no per-offer fee. Opening a listing to offers as a seller requires Pro or Premium.
Pro can open 1 active Offer Market and Premium can open 3. There is no separate per-offer or market-opening fee.
Price and trade proposals and the seller’s responses appear on the listing with explicit consent to public sharing. The seller updates the asking expectation and considers each proposal’s terms; the highest offer never wins automatically. Amounts in dossiers started privately are not disclosed to other buyers.
Offers and conversations started privately keep their access boundaries and are not moved into public history. Earlier Offer Room test records remain in a separate archive and do not create new membership rights.
Collectorium does not collect the listed item's price. Opening a conversation is not an automatic sale, title transfer or authentication; the legal effects of the parties' statements must be considered separately.
Pro includes 1 Board post per month; Premium includes 3. Each post is published for 72 hours. Board publication is currently available to accounts in Türkiye. While your monthly or annual membership is active, allowances reset at the start of each UTC calendar month. Unused allowances do not carry over. One allowance is used only when an approved post is actually published. Replies are free. Free accounts and members who have used their monthly allowance can choose a separate 72-hour publication for TRY 30, including taxes. Publication and renewal are never automatic.
