Here are some great little money spells:
Throw a silver coin in the water upriver from your house, so that money is always flowing in your direction.
Keep some silver coins in a cauldron on your altar, asking your deities to never allow you to be without enough cash to pay your bills.
Tossing a silver coin in a well on your property (if you have one) is supposed to always keep you from going broke.
Leave a silver coin at the grave of a wealthy person with a request that you attain wealth. Bury it in the dirt near the grave so no one else removes it.
Make a money pouch: use an old-fashioned change purse with a silver coin, a piece of citrine, a piece of malachite, some alfalfa, and some Come to Me Oil to keep the money always coming.
