Released long ago and now retired, Car Building Set (1503) is a vintage Duplo micro-set whose scarcity of complete sealed copies—partly due to original combo-pack distribution—has supported value retention, and it trades in a thin, niche market with limited broader demand and elevated liquidity volatility.
