Love and hugs Adelina!  Why a hole In your dollar?

I have found still interesting one:

1921 "PEACE" DOLLAR

Notes:
Following the death and destruction of World War I, peace became a priority in America and throughout the world.  Following some nudging by a numismatist named Farran Zerbe, America began issuing a "Peace" Dollar in 1921.  Unfortunately, by the time the original concept turned into the finished product, "PEACE" became a small word relegated to the bottom of the back of the coin.  The 1921 Peace Dollar was struck in very high relief, giving the coin an impressive, medallic appearance similar to that seen on the "High Relief" $20 Gold Pieces of 1907.
