No, they will be issued in order. If Carter is still alive, they will wait until he dies and then issue Carter, Reagan, Bush (also most likely expired by that time). Yes, as we move into the modern era of Presidencies there will be years, maybe even decades, where no coins are issued.
Are you sure about that? I thought I read that those living would just simply be skipped......maybe I'm wrong though.
The law is unclear about whether or not a living president can be skipped. It can be interpreted either way. However the list of Presidents and when they will be issued that the Mint published may give a clue as to what they have planned. The list originally ended at Nixon even though Reagan was already dead. Then when Ford died the list changed to include Ford but still didn't include Reagan. I would take this to mean that they do not intend to skip over a living President. As to the second question, on that the law is clear. Once the last qualified President is honored the program ends. If the next president dies less than two years from the last scheduled one he won't be honored. And if they die after the program ends they will not be honored. ‘‘(8) TERMINATION OF PROGRAM.—The issuance of coins under this subsection shall terminate when each President has been so honored, subject to paragraph (2)(E), and may not be resumed except by an Act of Congress. Paragragh 2 (E) ‘‘(E) LIMITATION IN SERIES TO DECEASED PRESIDENTS.— No coin issued under this subsection may bear the image of a living former or current President, or of any deceased former President during the 2-year period following the date of the death of that President. This is the section that deals with the order of issuance (3) ISSUANCE OF COINS COMMEMORATING PRESIDENTS.— ‘‘(A) ORDER OF ISSUANCE.—The coins issued under this subsection commemorating Presidents of the United States shall be issued in the order of the period of service of each President, beginning with President George Washington. This is where the question about skipping comes from. Since Reagan is dead he should qualify, but Paragraph 3 (A) requires the Presidents to be honored in the order they served. Honoring Reagan would put them out of order because Carter served before him. Of course the chances are quite good that both Carter and George H W Bush will die in time to qualify for coins which would make it a moot point. (It is unlikely Clinton, Bush or Obama will die in time to qualify.) Both Carter and Bush are 85 years old and so far only two presidents have made it to 90 years old. They would have to make it as well in order to not qualify. Clinton and G W Bush only have to make it to 68, and Obama only to 53.
