This is what Pottermore says: "Once you’ve been to Diagon Alley and opened a bank account at Gringotts, Ты will be дана 500 Galleons. Ты won’t receive any еще money for HARRY POTTER and the Philosopher’s Stone, so be careful how Ты spend it. You’ll receive your Далее allowance of Galleons when HARRY POTTER and the Chamber of Secrets becomes available to explore. How do I get еще money? Money is hidden away in various parts of the story (see 'Collecting items') so keep an eye out when you’re exploring different chapters and Moments. Anything Ты find will be added to your Gringotts account but, once you’ve collected all of the Galleons, there will no еще to find in HARRY POTTER and the Philosopher’s Stone. You’ll have to wait until HARRY POTTER and the Chamber of Secrets to receive and collect еще money."
So except your Gringotts account & the Galleons Ты find, there will be no еще money for the 1st book
