7/9/17 The Difference between Replica, Copy, Duplicate, and Reproduction
In best usage, a replica is a precisely detailed copy. Originally, the term denoted a copy made by the original artist, but that sense is lost in American English. It has come to denote a model, especially on a smaller scale <a replica of the Empire State Building>. A duplicate is an exact copy. A reproduction is a close copy, and especially one made after the original is no longer available.
