The special case of money
Money is always uncountable in English, even though in practice it's counted in dollars or bills: it's always "How much money do you have?", never "How many money."
How to ask about price
To ask how much something costs, you use how much without needing to say "money": "How much is it?" "How much does it cost?"
Common mistakes learners make
Using "how many" with money because you're thinking of the units (dollars, bills) instead of the general concept, which is uncountable. It's also common to use "how much" to ask about people, when it should be "how many people," since people are counted one by one.
