A 60th-anniversary Building Bigger Thinking subline piece, Rainbow Fun (10401) has shown modest post-retirement gains historically, and because its parts and anniversary tile were widely used and the Classic theme is frequently refreshed, it appeals more to completers than to buyers chasing scarcity-driven upside.
