MANTL
Grail slabs, pooled — ownership you can join
MANTL turns headline-grade cards into funds you can own a piece of — not fantasy picks, but real sleeves with published NAV and disclosed holdings.
Live fund
MANTL Alpha I
This is where MANTL started — a real sleeve of graded inventory, marked to market and fully disclosed. No teaser: you can open every line in the book, trace how we got to NAV, and see the actual slabs behind the numbers.

What we do
- Collect — We launch themed sleeves of authenticated, graded cards (PSA and similar), targeting liquid segments with observable comps — rare pieces, clear theses.
- Value — NAV is driven by a documented pipeline: identity and population from grading data, market comps (e.g. eBay), grade curves, scarcity adjustments, and a liquidity discount before fund-level NAV.
- Own — You own an interest in each offering you join; economics track aggregate performance. Holdings are disclosed so you can see the cards that back your position.
