Unfortunately, accurate retail and value pricing for all sets released in 1955 is unavailable. Production was highly limited during this period, with distribution primarily in Denmark and some availability in neighboring countries like Sweden, Germany, and Norway. Additionally, records from this period are scarce, and original pricing information is not well-documented. As a result, determining precise values for these sets remains a challenge.

About LEGO System i Leg Supplemental

Supplemental sets are the parts packs of LEGO System i Leg, the System of Play that LEGO launched in 1955 to turn its bricks into one connected toy. Builders bought them to add more of the parts they needed, such as bricks in each size, windows and doors, roof bricks, plates and corner bricks. Others add details for the town plan of the time, such as Esso petrol pumps and signs, light masts, letter bricks, Danish and international flags and beams printed with Danish shop names.
1955 LEGO Sets
1955 marked the debut of the LEGO System i Leg—“System of Play”—the foundation of the modern LEGO philosophy. Introduced at the Nuremberg Toy Fair, the concept unified LEGO sets under a single scale and theme: a buildable town with houses, vehicles, and streets. Though early reception was cautious, it established the guiding Principles of Play later adopted companywide. LEGO also entered new markets in Sweden and Germany, broadening its reach beyond Scandinavia.
