Obverse and reverse
Avers [ of; French (from Latin adversus ) ] is the name for the front of a coin, a religious character or a medal, in contrast to the back ( reverse ). The Latin word means forward facing. This front ( image and / or text) is usually the main page.
The numismatist or faleristics denote the embossed by the lower punch page as averse ( and screen). In the literature usually abbreviated as, or av. The reverse, however, is referred to as reverse (also page value ).
In heraldry and vexillology, the terms obverse and reverse are for the specification of front and rear internationally increasingly used.
