There's a protrusion on the top of the left wheat stalk... This is the first time I've seen something like this before. Can anyone identify what type of error it is, if it is one? http://www3.nf.sympatico.ca/donna.penney/coins/1951Error.jpg
Thanks folks, it was the first time I've seen anything like this and the consensus appears to be "die chip"... mystery solved.
