I will offer my two cents...Be that what they may...Not only am I Scottish Proud, but also a Veteran and a Mason, I don't understand the Masonic Coin idea for a kilt pin? Are you trying to affix a coin to your kilt in place of a Kilt pin? Why not just order the Masonic Kilt Pin and wear, or you can customize a smaller version by possibly affixing it to a small sword with some JB Weld I know my Kilt Pin I wear is a Bronze Star Medal in Miniature that is glued to a Silver Sword. I did however purchase a Past Masters Kilt Pin, it looks like the silver sword with the Masonic Past Masters Emblem on it. Just a thought. But if you use the epoxy JB Weld, use the two type mix and apply...it does work
