Different token types with exact same coin mechs

Hi

This thing is bothering me for some time now. There are different token types disregarding regard lettering, which also have the same dimensions, weight, magnetism, edge, etc.

This actually means, that some different token types can actually be used on the same spot (eg. carwash station). Here is one, that I found today in our capitol Ljubljana, and that I know for a fact are also used at different automatic carwash providers in capitol: https://en.numista.com/catalogue/pieces161830.html

Another perfectly the "same token" (just with different lettering) here: https://en.numista.com/catalogue/pieces38613.html

First of this token type I got from Germany.

1.st: Is there a single word that describes "different token types with exact same coin mechs", or maybe we can make one up here on Numista, like maybe "interusable token"?
2nd: I would propose to upgrade Numista with special section, where tokens with only the same mechs are interlinked. Only after all criteria is met can two or more of such coins or tokens be interlinked. Current section "See also" is more liberal and it should stay this way.

I hope this thread shall not venture in the part where we proceed with conversation over which cheap coins can replace 1 EUR coin in automatic vending machines...
