B+

Investment Grade

⏳ Retired

The LEGO Architecture theme has proven to be a solid investment over time, with many sets appreciating significantly after retirement. Trafalgar Square, with its iconic status and reasonable piece count, has the potential to follow this trend. The set's retirement makes it more attractive to collectors, and the stable price suggests it's currently undervalued. However, its relatively low piece count compared to other Architecture sets might limit its long-term appreciation potential.
