It is a 1947 canadian nickel. it is not round. it is more of a dodechahedron. (twelve sides) there is a dot under the seven, and there are dots all around the edge of the coin, like a border. on the tails side, there is a beaver on a log/rock, with 5 cents written above it and a maple leaf on each side of the lettering. underneath the beaver is CANADA and 1947 under that. and on the left side of the coin is K.G. on the heads side is some guy with GEORGIVS VI D:G:REX ET IND:IMP: writrten around him. oh, wait a second. the dots around the edge arent dots. theyre like spikes, little roundish rectangles coming from the edge of the coin. i don't know coins very well. i hope it was detailed enough for ya!
