Another common coin set are Peso's. Outside the US Soccer is a big deal to Europeans and South Americans.
Their 1 and especially 2 dollar coins seem to like to jump outta their pockets. Many days did I make more than lunch money hunting down there 
A Euro is worth $1.38 face value...Its about as common as finding a clad quarter.

Wow, this is the first euro coin I found in 26 years of metal detecting. I have found tons of clad quarters though.
as MUD stated, the current conversion rate is $1.38 US for 1 Euro. Note though, that your coin is a 20 cent Euro. The sub-units for the Euro is 100 cents, so the current conversion rate for your coin is 0.276 cents US. To answer your question if this is a common find, I would certainly think not very common at all in the US
