smauggie Valued Member United States 271 Posts	Posted 03/05/2019 8:05 pm The interior of this mint mark seems rotated compared to the exterior. Also, the vertical bar of the letter D seems to be unusually thick. There are also some raised lines to the southeast of the mint mark which may just be slight die trails. I checked FS and Wexler and do not see anything matching this particular situation. Let me know what you think. The dark brown line in the field of the coin is a bit of a mystery to me as well. Thanks. Report this Post to the Staff

smauggie Valued Member United States 271 Posts	Posted 03/06/2019 12:06 pm I didn't say it was a trail die, and I am familiar with that (very well done) website. Given that it is not a trail die, what might cause the apparent streaks coming from the mint mark? Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 03/06/2019 12:19 pm All pre 1990 coins had the mint mark added to the dies by hand. So any location/shape/angle of the mint mark can happen. There is a recent thread thread on mint marks and RPMs. But on your coin note the die flow to the SE. That is the common direction for the die flow to fall in that direction. The older the die gets, the more die flow lines ill appear in that direction. It happens on the date as well. This is a normal event. The older the die the more die flow is visible. Sometimes these lines are polished off and new ones will appear. But the devices will be shorter in height. You can see the die flow lines the date on your coin, but the die is not as worn yet on your coin, but later coins from that die will show even more. Just die wear is the cause. Probably 250K of the last coins struck with that dill will show these marks. It is common. Report this Post to the Staff
smauggie Valued Member United States 271 Posts	Posted 03/06/2019 1:02 pm Thanks coop. That is exactly the kind of information I was looking for. I have been collecting coins for over 30 years but since I got my microscope I am seeing them in new ways, and it is cool to learn more about how coins are made. Report this Post to the Staff
