Thanks commems. I haven't read the legislation language, but this Coin Update article from last summer indicates the Apollo 11 coins would also be curved (like the BBHOF coins) with an added unique design component:
Quote:A total of four different commemorative coins would be issued under the program. This would include up to 50,000 $5 gold coins, 400,000 silver dollars, and 750,000 clad half dollars, each issued in proof and uncirculated qualities. The final coin of the program would be 5 ounce .999 silver coin with a face value of $1, struck in proof quality.
The bill requires the coins to be produced in a fashion similar to the 2014 National
Baseball Hall of Fame 75th Anniversary Commemorative Coins, with a convex reverse and concave obverse. The shape would allow the reverse to more closely resemble the faceplate of an astronaut's helmet and the obverse design to have a more dramatic display.
It is also included as the sense of the Congress that, to the extent possible without significantly adding to the price of the coins, the coins should be produced with the design of the reverse continuing over what would otherwise be the edge of the coins, such that the reverse design extends all the way to the obverse design.
