Could this be a strike through or possibly from a planchet finger? I think that is what they are called....
If the direction of the hit on the "Y" happened to be in the same direction as the anomaly, I might be inclined to agree with you. However, it is not. @Kaye is the anomaly raised or recessed? If it is raised, then it is possibly the result of a die gouge. Chris
Well, I looked as closely as I could, and it does not appear to stand higher than the coin surface. I would say there are grooves with some metal left higher [the wider parts], but not raised above the original surface level.
