Real coins in 9ct gold cufflink settings

These Spanish real coins had been purchased as a set of cufflinks, where the cufflink part had been soldered directly on to the coins.  I was asked to make 9ct gold settings instead with the design to be similar to an existing set with half-real coins.  Good access to the back was required.  I used commercial cufflink components in the design which holds the coins securely, but undamaged.
