Origin and etymology of “same species/different species”

They are originally common words. “Homogenous” refers to “the same type,” and “heterogeneous” refers to “different/different types.”

Since then, the term has been used to refer to types of goods.

For example, if you are exchanging an acrylic stand for character A and an acrylic stand for character B, it is a “like-kind exchange,” and if you are exchanging A’s rubber strap and B’s acrylic stand, it is a “different kind exchange.”

There is also a pattern called “same-different-kind exchange,” where any goods from A are OK.
This is completely a matter of personal preference, but roughly speaking, people who collect goods can be divided into those who “want to collect goods of the same type (complete)” and those who “want to collect goods of the same character, regardless of type.” people exist. Therefore, this division is relatively important.

In the case of “different kind exchange”, there is often a difference in the list price of the goods (on average around 200 to 300 yen).

In that case, there are cases where you pay the difference between the list prices to the higher list price, which is called “difference settlement,” but this increases man-hours and may cause trouble, so you may have to adjust the number of goods, etc. It is more common to ensure that there is no difference (or no payment is required).
