Mystery bricks
Timeless Rarities - www.rarities.no - Last Updated: 09.04.2026
These bricks are still a mystery, not matching any other known bricks or moulds. When and why these were made we do not know, so we can only speculate. The bricks were found in a lot with some factory mistakes, so they may have originated from an employee. Maybe these bricks were made while a mould was being retooled? Could explain why they appear as a mix of different moulds, but no exact match.
The 2x4 does not say LEGO anywhere, but the colour and marble matches the 2x2. The 2x2 does say LEGO underneath, but it does not have hollow studs, same goes for the 2x3. The closest match would be the single logo mould. Maybe this was the mould they were about to make it into?
On the top 2 pictures the bricks can be seen next to a common blue hollow brick. On the bottom two pictures the bricks can be seen with the closest matches from actual production moulds.
