The first thing that became obvious was that the Equestrian coins weren't gold. Or, at least not pure gold. Erin had no idea, they could be brass for all she knew of metallurgy. Or perhaps they were some mystery element found only in Equestria. The bits she had earned yesterday were a bright golden in color, similar to the gold coins from Earth, but slightly paler. They were also lighter, she decided after hefting a few. She didn't have a scale, so she wasn't sure by how much, but they definitely weighed no more than half as much as a similar volume of the pure gold coins she had received from the Harmonics team.
