Does the US still mint 50 Cent Coins?

Could you please clarify for me if the United States government is still producing and distributing fifty-cent coins, or have they discontinued their production for any particular reason? I'm curious to know if these coins are still considered legal tender and if they are still widely circulated within the country. Additionally, are there any plans in the future to change the production or distribution of fifty-cent coins? Thank you for your time and assistance in answering my question.
