A copy refers to a version that is out of print and cannot be copied, as well as a version made or produced in other ways. For example, a 65-year-old model of Jim Liang, made of copper and covered with veneer, can no longer appear, so it may be copied with new technology or the original, but it is obviously not a 65-year-old model. I once had a copy of antique silver in my hand. Moreover, replica versions are all symbolic reproduction products that have been launched, which may be a person, a year, a month or even a certain day. And it must be aimed at another specific thing, from the details of design, materials and so on, and it may be innovative in some way, that is, to express the nostalgia and respect for that product.

It can be inferred from the above that the replica version has properties that the ordinary version does not have.
