The Commission of Fine Arts, which consists entirely of Trump appointees, has approved a proposal for a 24k gold coin depicting President Trump. The bipartisan Citizens Coinage Advisory Committee last month refused to consider this coin. Members said in interviews that they opposed putting any sitting president or living past president on a U.S. coin, even a collector item like this one. The last time that happened was during the Coolidge administration.

The portrait of Trump is based on a photo taken by the chief White House photographer and is now hanging in the National Portrait Gallery. It shows him leaning over his desk, with his knuckles on the desktop. The other side of the coin would show an eagle.

Members of the coinage panel said in interviews that they opposed putting any sitting president or living past president on a U.S. coin, even a collector item like this one. The last time that happened was during the Coolidge administration.

“Only those nations ruled by kings or dictators display the image of their sitting ruler on the coins of the realm,” the coinage committee’s acting chairman Donald Scarinci, said in announcing that the coin would not be on the panel’s February meeting. The New Jersey Democrat has served on the committee for 20 years.

Gold coins like these are not intended for circulation. They generally are sold by the U.S. Mint for several thousand dollars.

Even without the Citizens Coinage Advisory Committee’s approval, the Treasury Department has the independent power, without congressional authority, to mint coins like this.

How big would this coin be? “I think the larger the better, and the largest of that circulation, I think, would be his preference,” said the president’s executive assistant. He also said that it was “fitting” to have Mr. Trump on a coin commemorating the country’s 250th anniversary. No date has been announced for sale of this coin.

The question for stamp collectors is whether stamps featuring Trump will be next. No living person has been honored on a U.S. stamp, although living people have sometimes been used as models.
