1918-P wide collar error caused by vertical collar cracks (Coin World article)

[ericodapro]

Mike Diamond determined this to be "a wide collar error and the only one I've found associated (and caused by) a series of vertical collar cracks. I guess another way of framing the diagnosis is to say that the coin has four retained collar cuds. A normal cent has a diameter of 19.05mm. The E-W diameter of this 1918 cent is 19.46mm and the N-S diameter is 19.44mm"
