The two most important attributes of a modern coin for the typical collector are the coin's theme and design. A collector who finds those aspects of a coin compelling and complementary is likely to want the coin.

Of the myriad themes depicted on modern world issues, astronomy and space are certainly among the most popular.

Exactly why so many coin collectors have an interest in astronomy is unclear, but it could have something to do with the fact that many people started collecting coins when they were children. Children are often fascinated by space travel, the solar system, and the planets, especially if they were young when the Apollo 11 landed on the moon in 1969, or at the time of John Glenn's space orbit in 1962.
