How to make a magical two headed coin

Step 2 Attaching the two Coins

First, take each coin, and sand the "Tails " side until it is pretty rough, this gives the glue something to hold onto.(first picture)

Then, put superglue on all parts of the "tails" side of one coin, and attach the other one to it.

Now, you have 2 coins stacked, and super glued together.
