HELSINKI SUMMIT UPDATE: We still don't know exactly what TRUMP & PUTIN agreed to.— Kenneth P. Vogel (@kenvogel) September 2, 2018
BUT, I can now report that the White House Communications Agency's team did in fact produce a challenge coin commemorating the occasion.
Alas, it does not feature the faces of Trump & Putin. pic.twitter.com/lsd2yfR5Rl
Helsinki’s cathedral church is incused in the center of the commemorative coin with American and Russian national flags on the background. The names of the Summit participants are indicated around the coin, the date and the inscriptions in Russian – “meeting on a high level”, in English – “Summit of the White House and Kremlin”. The White House and the U.S. President airliner and his seal are depicted on the reverse side.
On May 22, The New York Times reported that the White House Communication Agency issued a commemorative coin dedicated to Trump’s meeting with Kim Jong-Un.
