How much did the first monopoly cost?

The first edition of Monopoly, originally called "The Landlord's Game," was created by Elizabeth Magie in 1904 and was intended to illustrate the negative aspects of land monopolism. However, the game as we know it today was published by Parker Brothers in 1935, and it was sold for around $1.50 at that time. Adjusted for inflation, that would be approximately $30 today.
