DIY: Spring's Uberhuge earrings

I have been looking EVERYWHERE for silver coin/disks to make my own version of these. Cannot find ... but when I do I will be posting the finished product.

I found these on whowhatwear.com and felt an immediate DIY project coming on. I actually used to make and sell leather earrings like this at the Valley Markets when I lived in Brisbane ... I have gotten lazy in my old age. Need to start DIYing again.
