The United States Mint will release a commemorative gold coin in April that will feature Lady Liberty as a black woman, marking the first time that she has been depicted as anything other than white on the nation’s currency.

The coin, with a $100 face value, will commemorate the 225th anniversary of the Mint’s coin production, the Mint and the Treasury Department announced on Thursday. Going on sale April 6, it will be 24 karats and weigh about an ounce.

It is part of a series of commemorative coins that will be released every two years. Future ones will show Lady Liberty as Asian, Hispanic and Indian “to reflect the cultural and ethnic diversity of the United States,” the Mint said in a statement.

The announcement comes at a pivotal cultural moment for the United States, a week away from a transfer of power, following a bruising election dominated by debates about immigration, race and political correctness.
