I was over looking a year for a Lincoln Cent one time it had a "inverted cauliflower ear" above his normal ear type of indentation. Well, I found one in a CoinStar machine recently. A whopping $0.92 was in the rejects bay of the machine.
For funzy, I might make a Stereo microscope from a 3D printer with plans of showing the deep well of the one I mentioned and a normal one. Maybe get Legos Electrical circuits for LED's, hmmm. Post a Lincoln? Okay, here's this one.
first edition error coin book from well known collector..and one of a rare breed having the 145 P, D, S cents!!
Thanks for the kind words. I certainly learned a lot by photographing, thinking about, and sharing my coins. I just reshot this one to attempt to capture the luster. I showed a different picture of it before in post #4203.
