i just found a 1971 Kennedy Half Dollar that appears to be struck multiple times. On the face just below the letters and number all the way around the coin is a mark that has about 5 parallel lines in it with relief. There are also other places on this face where there are portions of the same lookiing mark. Anyone ever heard of this before.
Welcome to CT Brian. Here is a standard spiel I give new members about photos. You should always post FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and is easily enlarged by clicking on it. Always show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Crop out superfluous background so just the coin shows, and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck.
