No, silver coins are alloys.
A compound is composed of two or more elements combined at the atomic level. The ratio of one element to the other(s) is always fixed. Water is the most familiar and classic example of a compound. It's composed of two gases, oxygen and hydrogen, with one atom of oxygen joined to two of hydrogen at the atomic level - i.e. H20. A compound can only be separated into its component elements via a chemical process; for example water is usually separated by a process called electrolysis.
An alloy is a combination of two or more metals, usually created by melting them and mixing them together. The proportions can vary depending on how much of each metal went into the mix. For example, coin silver is 90% silver and 10% copper, sterling silver is 92.5% silver and 7.5% copper, US cupronickel coins are 25% nickel and 75% copper, and so on. Alloys can frequently be separated into their component metals by mechanical processes such as heating or the use of acids.
One example of a compound that contains silver is silver nitrate, AgNO3.
The correct compound for Ag2SO3 is silver sulfite.

The compound with the name AgClO4 is silver perchlorate. It is composed of silver (Ag) and perchlorate (ClO4-) ions.
AgI is an ionic compound, specifically a metal halide. It is composed of silver ions (Ag+) and iodine ions (I-), which are held together by ionic bonds.
Yes, what little silver is in (or on) the coin is real silver.
Compound
The compound formula for silver hydride is AgH.
Silver oxide is not an element. It is a chemical compound composed of silver, oxygen, and sometimes other elements. Silver is the element while silver oxide is the compound formed by the reaction of silver with oxygen.
Silver nitrate is a compound composed of the elements silver, nitrogen, and oxygen. It is not a pure element, but a chemical compound.
Moneta d'argento is an Italian equivalent of the English phrase "silver coin." The phrase translates literally as "coin from silver," "coin in silver" or "coin of silver" in English. The pronunciation will be "mo-NEY-ta dar-DJEN-to" in Pisan Italian.
If the coin is an "S" mintmarked silver proof coin, it's 90% silver.
