What Are the All Time Most Exact Dollar Values?

Baseball's selary structure is set upright where you just don't get paid much in your early years of service time. But we got a question from listener matthew, who says what about the all time most exact values? Is there any fun in searching to see if a player, in a year, or a contract or a career, made close to how much he should have made? So i look this up with help from people at baseball reference and fan grafts, hopable statsites working together.
