Sell-Side Art Advisory · Auction & Private Sale

Sell rare works for what they're worth.

Rarity Advisors guides collectors, family offices, and estates through the sale of exceptional works — at auction when the market should set the price, and privately when discretion serves you better. One advisor. Your side of the table.

Our Approach

One mandate: the strongest outcome for the seller.

We are not loyal to a channel — we are loyal to the result. Every work is assessed on its merits, against both markets, and routed to the venue most likely to deliver the strongest outcome with the least friction. No house quota. No in-house buyer waiting in the wings.

Auction

When the market should set the price.

For trophy works and active artists, competitive bidding usually wins. We select the right house, negotiate favorable terms on your behalf, and run the process — so the gavel works for you, not against you.

  • House selection & terms negotiated on your behalf
  • Estimates, reserves, and guarantees structured for you
  • Catalogue positioning & bidder targeting
  • Post-sale settlement & tax documentation
Private Sale

When discretion serves you better.

For works where exposure carries risk — sensitive estates, fragile markets, or a desire for privacy — we place directly with a short list of pre-qualified collectors. No public record. No catalog. The transaction stays between buyer and seller.

  • Discreet, targeted approach to vetted collectors
  • Family-office & private-collector network
  • Negotiation, viewing, and condition management
  • Escrow, transfer, and clean documentation
How We Work

One process. Either path.

Whether we end up at Sotheby's or in a Manhattan apartment, the first four steps look the same — because the goal is to recommend the path before we walk it.

01

Confidential valuation

Provenance, condition, comparables. A defensible private-market and auction-market value, side-by-side.

02

Side-by-side outcome

We model the likely outcome for both paths — auction and private — and recommend the route that delivers more for the work and the seller.

03

Sale execution

House negotiation and lot strategy, or direct collector approach and quiet placement. You stay protected.

04

Settlement & transfer

Escrow, condition, shipping, insurance, and clean documentation for your records, advisor, or estate.

Who We Work With

Built for sellers who want guidance, not a pitch.

For Collectors & Family Offices

Refine a collection. Raise liquidity. Rotate an allocation.

We sit on your side of the table — weighing both auction and private outcomes for each work, and running whichever sale serves you better. No house quota. No in-house buyer.
