A late-2018 Collectable Minifigures Series 18 entry tied to the 40th-anniversary wave, Birthday Party Boy attracts steady interest from completionist collectors due to its unique prints and accessories, and constrained single-wave supply supports moderate post-retirement appreciation while broader appeal limits upside.
