Qiqirn seem to wear "coins" on their earrings - have you ever looked? It would be fitting for a race that seem to love money, gems and all things of value - things which they look to carry on their persons at all times.

Have you ever zoomed in on these coins? They look to have a face on them of an eagle wearing a crown. I have taken a screenshot which I'll try and upload from my PS4 - but do we have an origin for Qiqirn (are they from the East?) and perhaps where this currency, if it is, comes from?
