Three of Coins shows a young craftsman working in a cathedral. His supervisors or patrons are holding the architectural plans and inspect his progress so far. They have given him the opportunity to show what he can do, respecting his input and acknowledging his contribution. They've invested in him, and as a result he can develop his skills and his career. The craftsman learns from their experience and expertise. Everyone collaborates as part of a team. All benefit. 

 

In summary, this card is about cooperation between parties on different levels. By joining forces, they complement each other and allow the creation of what neither party could have wrought by themselves. 

 

Also remember that for the creation of Coins (a.k.a. aspects in life related to work, health, prosperity, responsibility) it is essential to build on strong foundations and draw up a solid plan.
