It could also be interpeted as 7 copper PER PERSON, meanign that the total for Ainz and Narberal was 14 copper. So total cost was 14 copper, Ainz gave 1 silver, and got 6 copper in change.

1 silver = 20 copper

It also would be more likley taht a wierd number like 13...

in addition Sebas mentions in volume 5 (chapter 1)  that

1 Platnium = 10 gold

and so far I havent found and source to clarify gold to silver... I suspect 20 though
