Looks correct. Note on the reverse, you can see the Bakesley affect. Not on the obverse. How does this happen? During the setup process the Blakesley affect can be seen on one or both sides the rims on the coin. When just one side is affected, I feel the blank moved upwards a bit, just leaving one side showing that affect. The other side as normal as it was not affected because of the slight movement during the setup process.

Yes with that whisper of a Blakesley on the rev, looks legit to me. Nice fie @sam!

@Coop great info, I have noticed this before and have wondered why we sometimes see the Blakesley effect on only one side of the coin
@Spence Thanks!

@Spence Thanks! I am thinking it is caused by the coin rising up and hitting the hammer die for a microsecond. I think of it like playing tiddly winks. On the clip side it causes the coin to tilt in the process of being struck. Could be wrong here but think of how tiddly winks is played. |

No the blanks are turned into planchets with the proto rim added to the blanks:  The setup process rolls the edge to make a foundation of the rim before the strike. When there is not edge on that area, that does cause the proto rim to form on that area. (Called the blakesley affect) Cut blanks:  Turn the blanks into planchets by adding the proto rim:  Striking the coins:  |

@Makecents thanks! Yeah, it really does feel like I've hit a bit of a hot streak (especially with nickels). Besides all the errors and varieties, I also found 4 War Nickels, 7 buffalos, a 1957 proof, a few semi key dates, and a lot of AU/BU older Jeffersons this week. Sadly, will have to slow down pretty soon since the semester is starting up again and I have a lot of research obligations that I was putting off during the summer. Edited by SamCoin

@Coop love the animations! I had never put together that it was actually the proto-rim forming process that was responsible for the Blakesley effect! That makes so much sense now. I had always assumed it had to do with pressure during the strike, but obviously if there's a clip the opposite poll will not receive enough pressure to perturb a proto-rim.

Glad it helps. I try to cover a discussion often times from a different perspective. CoopHome: Why do some clips only show the Blakesley affect on just one side? |
