A replica is a copy that is relatively indistinguishable from the original. However, replicas have often been used illegally for forgery, counterfeits, fakes especially of money & coins, but also commercial merchandise such as designer label clothing, luxury handbags & accessories, and last but not least: luxury watches. In arts or historic cars, the term "replica" is used for a non-original recreation, sometimes hiding its real identity.
One definition of "replica" has emerged that defines one as a copy of an original object, that can only be made by the original company (or corporate descendent) of the firm that made the original object-any other sort of copy of an original object would be called a "reproduction" instead.
Comparing with the originals,replicas are cheaper,and the quality is not worse,more suitable for almost the people.
