Coins that displays the Solar system as a whole appeared as early as in the 1700 years. We can find then as summarized on one coin or issed as a multi pieces series. We can follow by them how our knowledge on the Solar system has changed during ages, and how our world in that we are all are living has become bigger and bigger.

The moons of planets are colorful parts of the Solar system. Their numbers are great, their orbital movement, eclipses and always changing ordering and conjunctions support unfailing experience for the observers. However- not counting our Moon -these can only be seen by telescopes. According to this, relatively small numbered coins and medals we have that depict the moons of planets.

The solar eplises that alwasy enthralled and even terrified people. No wonder that we can find them in the world of coins. Eclipses have severe effects on people. Consider the war between Lydians and Medes that was stopped when the totality occurred as reported by Thales of Miletus. We have also medieval scripts that report the effect of eclipses on unknowledgeable people. The description of Thomas dean of Spalato (Split, Croatia) says: „At the same time, A. D. 1239 on the third day from beginning of the month of June a wonderful and terrible eclipse of the Sun occurred, for the entire Sun was obscured, and the whole of the clear sky was in darkness. Also stars appeared in the sky as if during the night, and a certain greater start shone beside the Sun on the western side. And such great fear overtook everyone, that just like madman they ran about to and fro shrieking, thinking that the end of the world come.”

Lunar eclipses occur roughly the same times as solar ones. When they supervene they can be seen from much wider area. Therefore form a given place more lunar eclipses are visible then their solar counterparts. Their appearance are, although spectacular, less dramatic. Maybe this fact is responsible that hardly they can be found on coins.

The revolution of Solar System bodies around the Sun or the planets constantly produces spectacular events when two or sometimes more of them get close to each other as viewed from the Earth. They don’t really get to physical connection only from our perspective they look at the same direction. This is often called the dance of the planets. Our Moon is often involved but in other cases only a planet and a background star or galaxy plays the role. The brighter the object involved in conjunction the greater affect it has on people.

Ideas and beliefs built around comets changed significantly throughout history. Aristotle in ancient times described comets as atmospheric phenomenon. That is why their sinister portent were not formed at that time. Their display on some coins exclusively motivated by the political will. In the Middle Ages superstition almost always considered them as a bad omen, their appearance predicted calamity. People fear them even at the beginning of the 20th century. In the present age of the fear of comets fades away, but this is due only in part to the beneficial effects of science. An insidious pollution, the light pollution, which simply clears from the sky the once terrific looking comets. For people who are living in big cities even brightest comets can be seen barely. One must travel long distances from the city now, to under dark skies, to see them in their former glory.

Minor Planets are important part of the Solar System, but we can hardly find them on medals. Caused by their dim light they can be seen only by telescopes, and therefore their discovery was delayed till the beginning of the 19th century.

Coins with meteorites came into fashion in the recent years. Now they are a new class of collectibles.
