Passage: In 2007, the United States Mint began releasing a set of half-ounce $10 gold coins under the First Spouse Program with engravings of portraits of the First Ladies on the obverse. When a President served without a spouse, a gold coin was issued that bears an obverse image emblematic of Liberty as depicted on a circulating coin of that era and a reverse image emblematic of themes of that President's life. This is true for the coins for Thomas Jefferson, Andrew Jackson, Martin Van Buren, and James Buchanan's First Ladies, but not the coin for Chester A. Arthur's First Lady, which instead depicts suffragette Alice Paul.

Question: what did a president that was issued a gold coin not have?
a spouse
