Really old Monopoly Game

I have a complete Monopoly set from my late grandmothers attic. They used coal to heat the house and had a fire at one time, so the game box is rough. Grandmother was born in 1905, so I guess this game is a second printing from Parker Bros. Ship, lantern, purse (or pocketbook), rocking horse, top hat, cannon, iron, car, shoe, thimble ,wood hotels & houses. I am trying to find out more about this game set. Marvin Gardens rent is $22, and there is a No. 9 on the end of the box. The patent # is 1,509,312.
