A coin that has been whizzed displays evidence of cleaning or polishing that shows parallel lines across the fields and devices. For example, you can use a Dremel tool to accomplish this. Chris
This is one that I had posted in Got wood thread. It is hardly circulated. It is in my collection somewhere, other wise I could post some much better pics. I also have a few that are only one sided and 2016' I believe. I really don't think these are from whizzing.
The OP's coin doesn't look anything like your coin. Note that all of the high points on the reverse are "bright white". To me, this is indicative of whizzing. Chris
I definitely hear ya on that one. I was trying to give an example of the same parallel lines. The op's coin has some different characteristics.
I try and learn as much as I can from @cpm9ball. The Man can show some extreme patients around here. He has answered more questions day nd day out. Than an OX plowing many a years Harvest. LOL I think that the areas in question "shiny" are actually part of the improperly mixed alloy, I am not sure what makes them so dark? In relation to the nickel. But, I think it is a contrast in 'tone' versus a depth of field. Sometimes I think you are just a grumpy old Man, then other times I actually listen to what you say. I appreciate ya! @TheHoff I think you have something there, what it is, I don't know. I will try to hunt my examples. Phil
These are roller lines , normally associated with dirty rollers as the coin metal sheets are being rolled to size. Whizzing is done with a tiny wire brush which will often leave a ridge of pulled metal at the edge of devices
