Very dramatic greaser
Due to low pressure, an adjustment strike will not only have weak details but weak rims as well. These dies were clogged with so much grease/debris that the metal could not expand into the recesses of the dies so it cold-flowed outward and completely filled the rim void. You will notice the same thick rim effect on high pressure strikes such as a proof coin which will appear to be much thicker than a business strike.

biokemist6 There seems to be an unending list of things that can go wrong when coins are made that it boggles the mind. Thanks for the explanation.
