Dwemer coins are a very rare currency of something with true mystery value and true historical value of the Dwemer socialization of their own society historical ruins. I know for fact the Dwemer coins are worth some heavy pounds for an Archaeologists that love artifact especially really an old rare currency.

The real question is we have the time to find, so why are Dwemer coins not in the game because there is a lot of Dwemer ruins to explore?

Maybe there’s more currency out there in Tamriel that can be unfolded and revealed one day.
