[Question] Every ayupan got "AEI" under the foot?

[CHAS_AYU]

I would like to ask about the "AEI" mark under the foot of ayupan.

Is that every ayupan must have that trademark?

Can anyone post some of your ayupan collection here, please?

Thanks

Asia Tour ayupans have AEI.

This was discussed in another thread a while ago. I think it had to do something with avex and some copyrite thing.
