One cannot live or photograph in New Jersey without patiences. This picture took a lot but others I have taken had much more. Yes the coins are all balanced on the sides. There was no photographic retouching or manipulations. To find out how I kept them in place you will have to ask for the secret. The coins are a proof set so the were flawless. When I was done I gave them to my niece.
