What "Most Valuable" Means Here
This ranking is designed for collectors comparing expensive key issues across the market. Fortress builds it from sampled public market listings, then ranks books by guide value rather than implying completed sold comps. That makes the page useful for discovery, relative pricing, and spotting books that are consistently offered at the top end of the market.
To keep Fortress viable on a lean operating budget, this leaderboard uses cached market snapshots instead of recalculating values on every page load. That lowers compute cost while keeping the rankings useful for broad market comparison.
