This is my interpretation of a scratch penny. I tried to make it as realistic as possible. I also made a back for the Scratch Penny which you can see by pressing space.
Some perks to this Scratch Penny are that it has both a front and a back. It is 100% pen and can be moved around with out distorting. This is because I used no go here block except to place the Scratch Penny at 0,0 and some variable ones so I could move both the X and Y coordinates simultaneously. It is also hard to counter fit because it is made with pen so even changing one number will make the whole coin look off.
