K40 eBay Chinese CO2 Laser Cutter & Engraver – Etching a Coin Sort of?

Please visit www.DIY3DTech.com for more information on this and many other projects! As in this episode we will be looking at etching a coin or at least trying to see what we come up with. As a viewer wrote in and asked about etching coins for a project and in general I can guess the results but hey you never know so let try it in mythbusters fashion and see what happens!

Safety Note: metal can be highly reflective in the IR spectrum and because you can not see the reflection does mean it is not there so this is not recommended!
