The Old Coin

It stays on my shelf in a special box
It is still and stiff like lizard
It is round and is very valuable
It can be traded for luxurious things
It has been by my side from the start
I will never lose it or give it to any one
It was given to me at birth from my grandfather
My grandfather died a week after
I have kept it through my life and I will always keep it
I keep it as my lucky charm whenever I am doing
Something important
It is old and dirty
It was made many years ago in 1966
I will always keep it close to me
