Do you have trouble distinguishing which coin is which? Then you need a coin buddy coin holder.
The coin buddy coin holder is a round metal container which opens to reveal a spring loaded slot for each denomination (5c,10c,20c, 50c, $1 and $2 coins).
To store your coins, locate the relevant slot and at the same time, slide and push down the coin from the outer edge of the container towards the middle until it is held in place.
To release coins, simply slide the coin(s) required towards the outer edge of the container.
