The front of this 1977 I noticed was lined evenly thoughout the front of the penny. The back of the penny there is none. Any idea what these markings are?    |

Either roller marks or improper alloy mix, but I do not know how to tell the difference. Because of the evenness of the spaces, I lean towards roller marks. Around 1980 +/- a few years, roller marks were prevalent.

Thank you Pete2226. Do you know if it is considered a error coin?

Roller marks are PMD. Improper alloy mix is a popular but common error that is unlikely to bring a premium. I agree that it has roller marks. |

Quote:Roller marks are PMD. I thought Roller Marks were pre strike damage. error-ref lists roller marks as being a Rolling Mill error. My understanding is that a sheet of raw stock will go through a rolling mill before being cut into planchets. Please set me straight on this. |

I read the rolling mill, is where the strips of metal for the coins is squeezed/pressed between a two rollers until they reach the correct thickness for blanking I read this for when I was researching rolled thin or tapered planchets

Either roller marks or improper alloy mix, Neither one. Improper alloy mix would be visible on both sides and it is too regular. Roller marks are also typically on both sides as well and don't showas differences in color. I would say this has laid on something for an extended period that has affected the toning on the one side of the coin. |

My feeling is that Conder is spot on with the analysis. Never saw that exact pattern, but have discovered coins in house cleanups that truly had not moved in 40 plus years and had a similar staining in the shape of whatever laid above them for all that time.

On the thread about enhancing natural toning someone posted two halves, a Barber and a Walker, which had been toned with newspaper. The letters actually showed up on the coins.

I was wondering if it was laid on a cancellation on a envelope for a time and it transferred to the coin?
