Hello to all. I hope you can please help me with this one. I've looked around online and asked some folks who couldn't make heads nor tails of this. I'm hoping my mentors can do so....I have a Lincoln Penny (anniversary 2009-D), OBV attached. It has what looks like (near) equally spaced perpendicular burst marks around the edge from about the 10 o'clock position to the 3 o'clock position. Looks almost like it would if saran-wrap was placed over the top of a can and pulled. In addition, the inner edge line disappears around the area of the Mint mark until almost to the last "T" (of TRUST) on the right side. Any idea what these are indicative of, and what they come from (possibly two different reasons?). Are they possibly a result of hard pressure OBV-die hit-marks. Please provide feedback when possible. Thank you in advance
They look like metal flow lines from an aging die. The die was simply wearing out and the continued striking of coins just makes them worse. These are also referred to as Late Die State (LDS) and when they get really bad, Very Late Die State (VLDS) coins. If you search on these, you should find lots of information.
The first US coin motto was found on a 1792 half disme and read: "LIB (erty) PAR (ent) OF SCIENCE & INDUSTRY"
Thank you for the insight....so much to learn...so, with that situation, it's probably pretty common. But, since the REV is a Lincoln Anniversary (Log splitting - Indiana?), good to keep for the Anniversary set? Thanks again.
As the two dies meet, the coin blank is loosely retained in a collar. Ten thousands or so to allow for slight expansion. These are most likely flow marks caused from a variety of factors. Slightly smaller blank, improperly retained collar, pressure, ect. A great question though, Welcome!
Thank you for the feedback and education. Since it is a Lincoln Memorial penny, I think I will just collar it with LDS on it, and keep it with the others in making sets. Suggestions are always welcome. Thank you and please stay safe!
