1990-P Cent, Wavysteps

Hi ,
They look like wavysteps to me. It is believed, by some to be a form of die doubling. If you can edit your title to this thread to include wavysteps, you will likely catch Chuck's attention as well as BJ's attention. They can also confirm this.

Have Fun,
Bill

Wow BJ. Great answer. That was really interesting! So does this mean the mint went to the single squeeze process and expected to eliminate double dies but instead didn't eliminate them and also created a new type of error?

Actually the MINT never said that it would eliminate the doubled die. The MINT in its 1986 statement said it would "avoid the possibility of hub doubling (doubled die) errors caused by misalignment of the second hubbing".

However, that did not happen and we do have a bunch of doubled dies. And yes, it did seem to create this new form of die anomaly.

Is it common occurrence? I am zeroing in on 600 known dies that have been affected with trails (wavy steps) with a starting date of 1982, which is the earliest known trail die. If we take into account all the working dies that were made during those years (1 million?), the percentage of dies affected is very low and comparable (or even lower) to the amount of doubled dies being produced by the single squeeze hubbing process.
