Halo1st Pillar of the Community United States 2775 Posts	Posted 12/29/2016 10:29 pm The inner ridge looks like Die Deterioration. The second ridge is the actual inner design rim. The third ridge created after the gutter is possibly slightly misaligned or high pressure strike. Wondering about the rim opposite this effect as it seems to taper off to nothing around the date. Maybe a tapered planchet or a bit of tilt to the die strike. Thanks, Doug. Report this Post to the Staff
koinpro Pillar of the Community United States 1781 Posts	Posted 12/30/2016 08:51 am This is Die Deterioration caused by the upset rim of the zinc planchets. Zinc has less give then a pure copper alloy and causes a lot of damage in this area. According to what the Mint told me sometime back in the 1980s when I first researched this effect, the higher the upset on the rims of the planchets, the faster and worse the Die Deterioration. I have an old letter on this from the Mint somewhere that I haven't seen in a couple decades that is probably easily found in my files. If I can find I'll post. Also some of the doubling on the upper rim is from a slightly misaligned die of no importance or value. This coin is a "spender". Edited by koinpro 12/30/2016 08:55 am Report this Post to the Staff
