The obverse side of a coin - is the side with The Queen's head on it.
All coins have two sides, an obverse and a reverse. The obverse is the front or the "heads" side, the reverse is the back or the "tails" side.
The term "reverse" refers to the back side of a coin, as opposed to the "obverse", or front side. On US coins, the obverse side is the one with the portrait and (except for the presidential dollars) the date. On foreign coins, it is not always easy to determine which side is the obverse and which is the reverse, although a good rule of thumb is that the side with the portrait, crest, or name of the country is probably the obverse.
The Obverse
Technically, the two surfaces of a coin are known as the obverse (front) and reverse (back). Informally, they are known as heads or tails. One side is called the obverse the other side is called the reverse. The obverse is general the side which features a monarch or president.

Normally the "heads" side is the obverse. That categorization is contentious when a coin bears the picture of the reigning monarch on one side, such as coins from Canada, Britain, and Australia. In those cases numismatists tend to call the design side the obverse and the portrait side the reverse, but that's not universal.
"Obverse" refers to the front of the coin (usually the side with the portrait), as versus the "reverse", or back, of the coin.
The back side is called the reverse. The front side is called the obverse.
