i just found a Canadian penny will post pics later its in pretty rough condition does any one know the value or is it just face value?
That year isn't rare. I believe there is a large and a small variety in that year. The small is the size of a U.S. cent. Since you said yours is in rough condition it probably isn't worth anything, maybe a quarter.
Your photos are good enough for this coin. Unfortunately the value is minimal. 1920 was a transitional year. The first year for the small cent but also the last year for the large cent.
