Hi all there r two pennies, 2018 and 2019 that has no rim. It's just smooth all around. What causes that
Striking issue. The rims are about the highest relief points of the coin and due to the very slight curvature of the die faces they are also the last areas that come into contact with the dies, they are the last areas to fill. So if the press is running a bit too fast, or the dies are spaced just slightly further apart than they should be the result will be weak or no rims. Rims can be weak from a fast running press because it takes a certain amount of time for the metal to cold flow into the devices and if the press is running too fast the pressure in not applied to the planchet long enough for that flow to occur completely.
Tnks ya learn smtng new everyday. Hope the Grammer police don't see this.... 1968 penny do you see a DD on the date and on liberty I used a Jeweler's loupe and then a pic the pic showed me more cuz you can zoom in on it
This looks like a normal cent Jimm. For this date (obverse design), the relief/fields look deeper than used starting in 1969. Dates for this obverse design appear sharp and defined, so perhaps the 'look' has you looking too hard on this one.
