Odds & covered floor
Every chase publishes per-tier odds and a covered floor — a real, gradeable coin worth at least the stated minimum in every pack.
For Deep Blue — Chase I, the covered floor is
$12 — every sealed pack includes a real,
gradeable coin worth at least that amount. Per-tier probabilities below are fixed when the
chase goes live; any change requires a new versioned manifest.
