My Coin

More expensive than it's worth,
Can't deny its might.
It has many identical brothers,
Could be lost through oceans;
But it's still here.

It only makes a sound when it drops,
A million people have picked it up,
But it has finally found me:
It represents its country,
And also represents me.

It was made in 2000:
A few bears on the front;
Queen Elizabeth II on the back.
It was once common
But now... magical!
