Double X-Rating Pen

Rate Your Friends On A Scale Of One to Ten!

The magician displays a regular Bic pen, stating that it is an "electronic rating pen" with a computer chip inside that rates people on a scale from one to ten. He then places a penny on the back of a spectator's hand, stating that "this is a one...the lowest you can possibly be."
 
Then... with just a tap of the pen, 
the penny then visually changes into a tiny minature penny!
 
But that's not all!
You can also choose instead to change the penny to a dime!
Or you can make the penny just disappear, leaving nothing in your spectator's hand!
 
Very visual magic will get big reactions when you change the penny into a dime.
 
Pen barrel color may vary.
