US Quarter Coin, 3D Scanned

This is a model of a us quarter coin. The coin faces have been 3d scanned, while the basic shape of the coin was modeled in Blender. The two faces and the base coin were then merged to one piece. More information about the homemade 3d coin scanner, which is based on a raspberry pi computer, can be found here: http://www.muellerr.ch/raspberry-pi-3d-coin-scanner/
