Anyone ever seen these lines before? I haven't. Thanks.

Not on a wheat, well I don't get to see many wheats. But I have seen something similar on Memorials and it could be from the rollers that flatten the metal. Clueless if that could be a thing with wheats.

Didn't realize this was in our Glossary. Still not sure about your wheat though

Roller Lines: These are very thin parallel striations, often seen on both the obverse and reverse going in the same direction. Though sometimes blamed on improper alloy mixture, these thinner, more even lines are more likely from dirty or damaged rollers from the rolling mill when it was reducing the planchet stock to the correct thickness for coin production. More commonly seen in the late 70s and early 80s.

I get a 404 error on the link to Mike Diamonds article... Appears the page is no longer available!!!

Normally roller lines appear as stains on the coin, like a woodie, but yours appear to be raised??? If they are raised it may be a die issue??? Time for a Mike Diamond visit???

Jim , there are some short flow lines in front of the bow tie that are reflecting highlights. The lines in question show no highlights. The lines do appear to be roller lines. Cool !

Thanks John... I think the shadows may be messing with me... Makes the lines look raised... One of those brain - eye interconnect issues
