I found this nickel with what I think is Mechanical Doubling on obv. and rev. Also has what I think is Die Chips in the cradles of the S's on the reverse. Now two weeks later I find it's twin from a different bank. I'm not experienced enough to figure out what is going on with these two coins and would appreciate your opinions. I hope I haven't added too many pictures. Please let me know if this is a problem. Thanks for your help. COIN 1  COIN2  COIN1  COIN2  COIN1  COIN2  COIN1  COIN2  |

There's a high possibility of me being wrong, but I believe these are machine doubled. With a die chip.

I agree. You can see MD on both sides of the coin.

You called it right, Bella. I would also compliment you on some very sharp well done photos.

Here is an Nickel overlay:    The date area is the only close to that area if there were a clash. Other wise it may just our eye playing tricks on us. |

Looks like MD to me. Nothing else

I probably did not phrase my question properly. As I understand it Mechanical Doubling is caused from bounce or improper movement of the dies on the strike. So I was wondering if it is unusual to see two almost identical examples of letters and numbers doubled in the same way? The die chips in the S's make me think it was the same dies for each coin. So does that mean these dies bounce/shift/vibration is exactly the same each time it strikes? I'm just wanting to learn as much as possible so please forgive me if I am asking a question with an obvious answer. |

I've seen different ones from strike to strike and some are similar. But the MD can vary a lot from strike to strike. Just depending on what causes the issue. Machine looseness can be in a a single direction or rotating direction. So there is not hard set rules for these. Just a normal die that has play in the machine.
The seeming letters are probably coin alteration. If it were a hubbing issue, the devices would be raised a lot more. The fields may have had some contact with another coin or pressed at one time or just leaving a mark.
