Gold for saving - my family always buy, is it still good idea?

In my family in Tamil Nadu, every wedding, every festival, we buy gold. My mother says gold never lose value, bank can fail but gold stays.

I am delivery driver, not big salary. Every year I put some money in small gold coins. My friend says better to put in mutual fund SIP, gold gives no interest.

Who is right? I don't want to say to my mother she is wrong unless I am sure. Please explain simply.
