Weird Unknown Error on Roosevelt DimeI don't know how to describe it but the fold ripple raised area keeps the design it is most likely PMD but I am not sure I got this with a bunch of clash I got from a collector this morning. I always ask you got any odd looking coins and most likely they do..
Note: there is no indention on coin all is raised The part between one united states and the ripple is level with normal height of coin and the ripple is raised. It has a Blakeley like effect going on above head on Obv. and other little things going on that made me think it may not be PMD. Any comments, suggestions, and feedback always welcome.

It is post-strike damage of some sort. Besides the "ripple" there are areas of flatness on both the obverse and reverse. The flatness is a good sign that this is only a damaged coin. Quote:It has a Blakeley like effect going on and other little things going on that made me think it may not be PMD. The Blakesley Effect cannot occur on a coin that does not have a clip or pre-upset distorition on the blank, though it does not always occur when there is a clip or pre-upset distortion. What you describe as the Blakesley Effect on this coin, is simply post-strike flattening. |

I assume PMD also I am just still confused as what could make it raised or rippled without indenting it. The rippled part is raised higher then the rest and no part of the coin is indented the other part between one and united states is level with normal height of coin In the picture I assume it might appear to be lowered or hit?

The "ripple" may have been caused by something pinching the metal upwards. I could be wrong, but that is what it looks like. Without the coin in hand, I'm only speculating.

Or the coin was heated and the separation of the clading was affected. The reverse is showing a black area on the left side of the torch.

How would excessive heat cause the flattening of the obverse and reverse designs?

Possibly by flattening down the raised area so it would work in a machine? That would be my guess.

For a scale, I use a AWS-100. 100g cap at 0.01g increments. Has a hard flip down cover and tare function as well. I think it was $26.00 US at online retailer. Just be sure to get the 100 g calibration weight to go with it. I like it.  |

I can't offer anything other then speculation, and I agree with coop...must have been heated at some point post strike. All-in-all it is very interesting coin! Seeing the damage come out rather than in isn't something I've seen before. I like it :)

Coop, I hadn't thought of that - excessive heat causing a large planchet bubble which was later flattened out.

I agree with Coop's theory.. This wasnt something that happened all at once but over time.
