They don't appear to be die gouges to me. You can see where metal has been pushed up (crater effect) to the west in the first two and to the northwest in the last two. This would lead me to believe it is PMD caused after the coins were struck despite the similarities. Chris
It's hard to properly orient the eyes to these coins, especially in photos this close, but the areas in question appear raised based upon which areas of the coin are raised. Judging by Bryan's response that they are indeed raised, then I would say they are definitely die gouges.
I keeep looking and looking at these images and they still appear incused to me. (Brain Games). Being incused on a device I was going to suggest abrasion/gouge on a hub.
i am going out on a limb to ask a dumb question... in the first 2 pics, if that was a die gouge, would it not continue through the wall of the suns rays? iin other words wouldn't it be one gouge start to finish? not look like it ended on one spot and continued on the other side?
Bryan, Here's a link that shows the same type of die scrapes, but on other denominations as well. You'll see the similarity, and it's easier to see the raised nature of the scrape in these photos- http://www.error-ref.com/die-scrapes.html
