Actually, the coin is round but it does contain an 11 sided polygon inscribed within the circle.
An eleven sided polygon is called a <span>hendecagon </span><span> (from the Greek </span>hendeka<span> "eleven"</span><span>)
EACH interior angle measures (180 degrees -(360 / number of sides)) =
</span>180 degrees -(360 / 11) =
180 degrees - <span> <span> <span> 32.7272727273 </span> =
</span></span> <span> <span> <span> 147.2727272727 </span> </span> </span>degrees
rounded to nearest degree = 147 degrees
