But that is part of the design on that mints coins. They mintmark punchings stopped in 1990. This is three years after that stopped. Could be slight Machine Doubling. (machine was not as loose as we often see the MD on coins. Then it gets real loose, then the devices are even more distorted with Machine Doubling, called push doubling |

the 'retooling' inside the 9 could be from polishing the die, usually we would not see such a shoddy field on a proof.

Most of what you are seeing is minor Machine Doubling. Remember the Machine Doubling affects the outer/inner edges of the devices. The tooling is often on the fields to enhance a wearing die, to enhance a weaken device area. Sometimes they are on the inner design, but they stand out like a sore thumb when this happens.  That is not what you are seeing on these images. On Proof dies, they only strike 3000 coins, (6K limited strikes) So die wear is usually not seen on proof dies. I have seen where a die dent was removed from a proof die once: Note the tapered affected when the fields was polished and the devices were smaller than normal?1982 LD Proof cent:  1960's proof die:  CoopHome: How can you tell if a die was enhanced or polished? Polishing dies makes devices smaller on the coins, enhancement enlarges areas on the coins. Edited by coop

thank you so much coop . coop this information is incredible thank you so much. coop interested in seeing a 1991. I am not sure right now if this 91 is the wide date or narrow one. I never marked them. my big unit is down.
coop is it normal to plate a penny with brass. When they identify the coin its suppose to be plated with pure copper.

People cash in on these. but I wouldn't do that. They can be found in circulated coins. They stand out like a connected to a light source in a bunch of non powered bulbs. Edited by coop

That is Machine Doubling. Note on the EPU on the reverse, the devices are incuse. (below the surface of the coin) When Machine Doubling happens on the incuse devices they get wider. (Just the opposite of raised devices. And the doubled dies are actually smaller is size:  Note the differences on the images above. But that is the simple answer. (But best to do this on a different thread for each coin) But always here to help. You might check out my answers to questions before they are thought up yet on these pages of CoopHome. Click on that and you will find 16 pages of discussions in the past that help new ones advance faster. There are hundreds of post there with thousands of images of how to advance faster in coin knowledge. Start with the last page first and work backwards, as this information is always the most up date. Note it turned blue above? Just click on the blue words on the site and it will open pages of past discussions. Enjoy. Edited by coop
