Thanks for the feedback..greatly appreciated..
For now....this is all that I have that show the rim at an angle..
Can't see any file marks ,..but maybe a few normal rim bumps might cause the flatter areas,..or maybe that's how the crack was progressing and possibly spreading out..
Take note that there are more than one raised line in that group of lines.,..it's just that the main raised line is much more noticeable..and now easier to see with this tilted view.. The collar crack probably initiated at the highest strongest central line..
Seems like any contacts would cause a raised area to go a bit flat with any impact....
It's the interesting striations and/or flow lines that keeps me guessing here..
I've just never noticed this type of collar crack or fine lines in the rim before on these large cents..(Alan Herbert's book explains the American cents variety very well)
so....
Check your large cent Vickies and post your collar cracks ..please..!!
