In the US it would still be fairly common for someone to know that "two bits" can mean a quarter, but it's not used much in common conversation. I don't know if this is just me, but I particularly associate it with a purposely colloquial or "old timey" register of speech. In my head I can envision a carny with a Foghorn Leghorn accent selling me a ticket to the Ferris wheel, "That'll be two bits, son".
