Set bottlenecks53 sets

The pin(s) with the fewest copies alive in each set (same set, edition type and variant), i.e. what gates completing it; pins tied at the minimum all count. Only Digital Display and Color Splash variants and Limited Editions qualify, and only under 120 copies alive. Filters narrow the sets; “Biggest gap” ranks by how far the bottleneck sits below the next-lowest supply of its set.
