[QUOTE="playpossum0985, post: 8266830, member: 23806"]Hey Mr. B, The lighting is natural light through my window taken with 16mp digital camera. I angled the coin to accent the lined and discoloration as best I could. It almost disappears at certain angles. What's confusing is that I've seen roller lines, but never stopping and restarting in a perfect curve that has the exact same diameter as the planchette itself. I've seen toning/ discoloration, this is proof that striations can cause toning. But why the shape of the striations and toning? It's almost like that portion of the planchette impossibly missed the washing process, you would think the tumbling itself would obliterate the lines, however the toning follows them exactly. Also, it is proof that die strike pressure is not a factor for "striation obliteration"... A missing link of sorts??? Maybe if someone can figure this one out anyway. Reverse has the striations also, exactly opposite of the obverse, however not as pronounced. Changed light source on these.
