Don Lueders posted two images, showing subtle differences. I have two chips, both without panes, that show a more distinct difference. Look particularly at where the end of the left horn touches the wheel.

All other examples of this artwork I've ever seen are like the first chip, where the horn ends in the middle of a spoke. The second chip has it going to the edge of the wheel. Trust me, it's not a registration error, or anything like that. It's different artwork. Anyone else ever seen an example of the second chip, or this artwork used on any other denoms?
