Trying to see what type of doubling or what it is that is visible on this coin. Also a bit of it in liberty. Thanks   |

Looks like a plating it's common for these pennies. A lot of times it won't even still have the copper. It will be broken and the zinc will be showing and rotting. This is my explication someone else might better explain

Plating seems to be widespread on zincoids, but I'm going out on a limb and thinking md.

This coin exhibits Die Deterioration Doubling. Here is an example of what you have if I am correct. This one also shows Plating Split Doubling. I described both effects in booklet I wrote in 1993, entitled, Doubling - Worthless Or Valuable. I think this was the first treatment on the subject though I may have written about it in CONECA's Errorscope earlier.

BTW, In that booklet I also noted that the Mintmark being punched into the die rather than hubbed, predisposed that area of the die into having plating splits more often and more dramatically that on other areas of the coin. A Mintmark punched into the die is at a sharper angle to the field than one hubbed into the die. Nonetheless, the zinc plating on business strikes is so thin that any copper plated zinc cent from the prior to and after the introduction of Mintmarks into the hubbing process, can have plating split doubling. (Mintmarks went into the master tooling starting in 1990 - today they are part of the plaster. Another interesting effect is when the plating springs back and piles up next to the MM.

Please correct me if I'm wrong. That means the date is md and the D is split plating. That's why most of the split plating is on the mm's, because of the depth the copper has to stretch farther. Good to know. thanks Koinpro.
