How can I make this Dropper script Drop bricks with certain Properties?

So I am currently using this dropper script for my Tycoon:

wait(2)
workspace:WaitForChild("PartStorage")
while true do
	wait(0.5) -- How long in between drops
	local part = Instance.new("Part",workspace.PartStorage)
	part.BrickColor=script.Parent.Parent.Parent.DropColor.Value
	local cash = Instance.new("IntValue",part)
	cash.Name = "Cash"
	cash.Value = 1 -- How much the drops are worth
	part.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1,0)
	part.Size=Vector3.new(1,1,1) -- Size of the drops
	game.Debris:AddItem(part,20) -- How long until the drops expire
end

I am wondering how I can modify this script to make it change the material and the color. Also when the bricks are created to make money the have studs and inlets so I am wanting to know how to edit that also. If you can help me along the way into making this happen you can help in the Comments! THANKS!

To change the colors, materials, and/or surface types, just set the property of it.

Color Example

part.BrickColor = BrickColor.new("Bright yellow")
part.BrickColor = BrickColor.new(24)

Material Example

part.Material = "Ice"
part.Material = Enum.Material.Ice	-- I recommend using enumerations (enums) whenever possible
part.Material = 1536

Surface Type/Surface Constraint Example

part.TopSurface = Enum.SurfaceType.Smooth
part.BottomSurface = Enum.SurfaceType.SmoothNoOutlines
part.LeftSurface = Enum.SurfaceConstraint.Motor

Enumerations can be a number value or a string name.
