A federal arts commission on Thursday approved the final design for a 24-karat gold commemorative coin bearing Donald Trump’s image to help celebrate the US’s 250th birthday on 4 July.

The vote by the US Commission of Fine Arts, whose members are supporters of the Republican president and were appointed by him earlier this year, was without objection. It clears the way for the US Mint to begin production on the coin, whose size and denomination are still under discussion.

“As we approach our 250th birthday, we are thrilled to prepare coins that represent the enduring spirit of our country and democracy, and there is no profile more emblematic for the front of such coins than that of our serving president, Donald J Trump,” the US treasurer, Brandon Beach, said in a statement.

Federal law says no living president can appear on US currency. But Megan Sullivan, the acting chief of the office of design management at the Mint, said the treasury secretary has authority to authorize the minting and issuance of certain coins.

She presented the coin’s final design at the commission’s March meeting on Thursday and said Trump had approved it.

“It is my understanding that the secretary of the treasury presented this design, as well as others, to the president and these were his selection,” Sullivan said.

The White House and the Mint did not immediately respond to electronic and telephone requests for comment.

The front of the coin features an image of Trump in a suit and tie with a stern look on his face. His fists rest on top of what is supposed to be a desk as he leans forward. Lettering on the top half of the coin spells “Liberty” in a slight arc. Directly underneath that are the dates “1776” and “2026”. The words “In God We Trust” are at the bottom, with seven stars on one side of the coin and six stars on the other side.

The reverse side depicts a bald eagle mid-flight with “United States of America” on the right side and “E Pluribus Unum” on the left side.

“I know it’s a very strong and a very tough image of him, and I think it’s fitting to have a current sitting president who’s presiding over the country over the 250th year on a commemorative coin for said year,” said commissioner Chamberlain Harris, a top White House aide to Trump.

The coin will be part of a “very limited production run”, Sullivan said, but the number has not been determined. The size and denomination of the coin also have not yet been decided, she said. Some commissioners noted Trump’s fondness for big things as they advocated for the largest size coin.

“I think the president likes big things,” said commissioner James McCrery II, who was the architect on Trump’s design proposal for a 90,000 sq ft (8,360 sq meter) ballroom addition to the White House. The fine arts commission approved that proposal at its February meeting.

Harris told McCrery she agreed with him. She works in the White House as a special assistant to the president and deputy director of the Oval Office.

“I think the larger the better. The largest of that circulation, I think, would be his preference,” Harris said, speaking of Trump.
