I was in Jerusalem a year ago and I went to a coin shop in an upscale mall. I asked them about this coin. They said "EVERYONE COMES IN HERE ASKING ABOUT THIS TRUMP COIN. WE DON'T HAVE IT! WE HAVE OUR OWN COINS!!" :)))
People visiting Jerusalem are always looking for souvenirs. I have made coins (Doubloons) to give out at Mardi Gras. Sometimes, it is cheaper to make those yourself than to buy them from vendors.
