Collectibles, with investment-grade discipline

Authentication is non-negotiable. A forged provenance or disputed restoration destroys value. The authentication chain needs to be preserved as structured evidence, not anecdote.

Custody and condition drive value. Climate, handling and conservation directly affect realised value. Custody arrangements and condition reports need to be tracked continuously.

Market depth varies by category. Rare watches trade through different venues than rare cars or memorabilia. Liquidity assumptions need to be category-specific.

Recurring costs erode returns. Storage, insurance, conservation and authentication renewals add up. Net realised return needs full cost attribution.

Collectibles carries 4 sub-asset overlays in the Reuben AI rubric registry: Classic cars, Watches and jewellery, Sports memorabilia and Trading cards. Those overlays are part of the 314 sub-asset overlays the platform maintains across 56 of its 68 native asset classes.

An overlay never reweights the parent rubric. It adds the extra scoring criteria, risk flags, document types and key term fields that only apply to that slice, so a classic cars deal and a trading cards deal are both scored on the shared collectibles rubric while each is still asked the questions specific to its structure. That is what keeps deals inside one asset class comparable to each other and to the rest of the portfolio.

Selecting an overlay at intake changes what the platform expects: the document checklist, the extraction schema for key terms, and the flags raised when a term sits outside the range the rest of your collectibles book has accepted. Nothing is retrofitted later by hand.

Every collectibles opportunity that moves through Reuben AI leaves a structured record rather than a folder of documents and a memo. The rubric score is stored with the criteria that produced it, each extracted key term is stored with the clause and page it came from, and every flag is stored with the reason it fired and who cleared it.

The practical effect is that the investment committee paper, the LP report line and the audit trail are all reading the same underlying record. When an LP asks in year three why a collectibles position was underwritten the way it was, the answer is retrieved, not reconstructed.

Collectibles sits as a core allocation for Family Office mandates, and is adjacent or opportunistic for 0 of the other fund types the platform serves.

That matters operationally because most funds do not hold collectibles alone. The moment a portfolio spans more than one asset class, comparability becomes the constraint: a position scored on a bespoke collectibles spreadsheet cannot be ranked against a position scored somewhere else. Running collectibles on the same rubric engine as the rest of the book removes that break.

Reporting inherits the same property. Portfolio monitoring, valuation cadence, capital account movement and LP reporting all draw from the single stored record, so a collectibles position appears in the quarterly pack on the same basis as every other holding, with the same evidence behind it.
