Little bit of MD but basically plain worn down die, nothing really special, but does make you really look!  |

I was leaning toward a deteriorating die but wasn't quite sure. Also some of the devices don't appear to be reduced so I was a bit confused. Thanks to you both.  |

Usually Die Deterioration Doubling has a faint image from the device in the direction of the closest rim, outward from center. This one based on the images from different light angle seems so worn out the devices are flowing in every direction. Also the "Ray" lines are an indication of die wear. The mint got their money's worth from this die pair. |

MD ( Machine Doubling) can be basically one of two things. It can be "doubling" due to a bounce when struck, the bounce strike comes down (offset a little) on top of the first strike - reducing devices from the first strike by leaving a flat, shelf-like "doubling" The second form of MD is from wear on the die. As the devices on the die wear, it is manifested on the coin as a "sloppy doubling". Think of a die and a coin as something with designs stuck into a piece of clay. Everything left on the clay (the coin) is opposite of what was on the something with designs (the die). All shapes are backwards and all reliefs are recesses. All recesses are reliefs. The Doubled Die is accidentally on the die when it is made, long before it strikes it's first coin. There are about eight types of Doubled Dies. The most sought after is when the devices are doubled with a wide spread from each other. |

Here's a couple of examples the first is a 1983 cent I picked up about a year ago. The other is a 1995.   |
