Assets do not reach investors by default. Every asset presented on Altherum passes a multi-stage review designed to answer one question from several directions: does this specific object deserve capital, at this price, at this moment? Many candidates do not, and the reasons they fail are as instructive as the reasons the others pass. This article opens the selection process, because a discipline that cannot be inspected is not a discipline.
Sourcing: category expertise first
Selection begins with accredited category experts — art advisors, gemmologists, wine and whisky merchants, memorabilia authenticators — who identify candidate assets or review those submitted by owners. Category expertise is not decorative: markets for exceptional objects run on connoisseurship, and the first filter is a person who has handled many comparable pieces. Assets without recognition beyond a single local market are generally not admitted, because a narrow collector base means a narrow exit.
Authentication and independent verification
Authentication follows as a separate step: provenance chains, certificates, condition reports and auction records are verified, engaging laboratories and authenticators without an economic interest in the outcome. Where confidence in authenticity cannot be established to the satisfaction of those experts, the asset does not proceed. The role of independence in this process is developed in our due-diligence framework.
Valuation across scenarios
Valuation methodology adapts to the class: comparable auction results for art and collectibles, laboratory certification for gemstones, documented maturation and cask provenance for whisky, population data for graded cards. In each case the output is not a single number but a documented view across conservative, neutral and optimistic scenarios, anchored to recent comparable transactions. That view informs the structuring, any floor price that applies, and the disclosures made to eligible investors. A single-point valuation is a rhetorical device; a reasoned range is an analysis.
The quiet filters: cost, exit, timing, concentration
Four further filters do less visible work. Custody economics: storage and insurance must remain a modest fraction of value per year, or holding costs erode the thesis — see how professional custody works. Exit realism: the question is asked before acquiring, not after. Market timing: we prefer to admit assets when their niche does not appear stretched, and we let segments pass. Concentration: we avoid building up exposure to single artists, single vintages or single geographies across the platform.
Valuation does not stop at onboarding
Once admitted, assets are revalued by independent experts on the basis described in each operation's documentation, with insurance intended to follow the updated appraisal, so that participants see a current documented view of value rather than a historic entry price. Material valuation movements are notified. The full journey from selection to exit is described in How It Works, and the class-by-class value drivers in Real Assets. Selection reduces avoidable risk; it does not remove market risk, and capital remains at risk throughout.
