The term "Ancient coins cover a very broadtime period study that spans over 2100 years on three continents: 650 BC to 1450 AD. This include the time from the first coins to the fall of Constantinople.

Ancient coins were made with many types of metals: brass, bronze, billon (debased silver), electrum (a natural gold-silver alloy), gold, lead, nickel and of course silver. The most common ancient coins are Roman coins minted in the third and fourth centuries AD (200 AD to 400 AD), so most ancient coins are 1600years old or older, and many are over 2000 years old.

Millions of ancient Greek and Roman coins were minted over span of a millennium. Thanks to the fact that Greek and Roman citizens would bury their coins for safekeeping, availability increases as numerous ancient coins are dug up from the ground each year in source countries such as Italy, Greece, Bulgaria, Turkey,and Israel.

Counterfeit ancient coins are a reality, greater than counterfeit modern coins because ancient coins were struck by hand and are much more varied in style. This makes them easier to fake. It is important to remember that most of ancient coins in the market today are genuine. There are several organizations that will authenticate your ancient coins if you have some doubt (or want some assurance).

Despite their history and beauty, ancient coins are typically not more costly than modern coins but less.
