It could either be a sign that gold has reached a top or it still has further to run: Lego introduced a mining-themed set this spring focused on gold production.
Sets 4200 through to 4204 feature excavators, mining trucks and even a complete mining operation with tiny gold Lego ore.
The large set will set you back $99.
Be warned, the safety precautions around the mine looks minimal.
