I would venture to say NOT a lamination problem because of the manner of production, a plated/core product(different than cladded). Laminations are produced from a miss-matched alloy mix, in modern times, with plating materials, that is almost an impossibility. That leaves two other possibilities,post or pre mint processing. I could be circulation damage, coin could have been twisted slightly causing a crack in the plating at that weaker spot. Or it could be the result of a stretched metal weakness during strike. The latter is referred to as "split plating" when it happens at the device edges. Either way, a weakened metal "split" at that point. Report this Post to the Staff

da Swampster Valued Member United States 420 Posts	Posted 05/10/2018 1:16 pm Since not stated, my first impression was the coin is pre '82 -- so split plating never even crossed my mind.. I did, however, lend just as much credence to a working hub issue as coin twist / weak spots cracking.. What it actually is though..? Waiting... EDIT: Upon re-examination, I have to go with a pre 1982 coin that at some point post-strike fell victim to metal fatigue cracking due to either incomplete mixing of or improperly portioned penny batter..
