Retired Creator Co-Pack 66173, a limited-value pack released under the Creator theme, has seen sealed copies become comparatively scarce due to its non-reissued bundle configuration, and that scarcity has supported post-retirement appreciation, while non-exclusive contents and easy substitution by newer brick kits limit upside and add volatility.
