Pennies minted before 1983 are made of mostly copper. With one of those and a few tools you can make a basketball tie tack. Or I can make it for you
Step 1: Get your materials
I started out by doing an image search on Google. Once I picked out the ball I liked I copied and pasted it to windows paint.
I resized the image a few times and printed it out. The goal here is to print out a ball the same size as a penny.
To find a pre-1983 penny simply pull out the pennies that are the darkest in the bunch. Of the three I pulled out, two were what I wanted.
Also grab 4 paper clips, some socket bits and, a pair of pliers.
