Treasure

My coin is very valuable and special to me.
I got this coin when I was born.
As shiny as the star upon us.

As twirly as the vine that winds its way around it,
My coin is as light as a pen.
Maybe not as colourful but as beautiful as the boiling sun.

The coin has a picture of the beautiful queen and the Castle of May.
The coin is as solid as a stone structure.
My coin is big, fat and as shiny as a watch in the sun.

It is as old as Etkins computer,
It is as boring as a rock.
Even though it is so boring it is my special object.
