Good morning, is there similarities in the 1985 and the 1985 d Lincoln Cent with the date and mint mark? The eight and the five on the d look a lot like the eight and the five on the Philadelphia. Is that even possible? There was no 1985 d RPM in variety Vista. In wexlers, there are two 1985 d RPM one going south one going east and both are not as thick as this d. I'm guessing environment smashed it down. On the reverse looks like die deterioration or a lot of Grease filled. Thanks again for the schooling.
Lets end the thought of environment damage. ED has to do with corrosion and usually only the toning on a coin. ED can cause surface damage but only porous surfaces and raised deposits that are stuck to the surface. The circular damage above the date is damage but not environmental. Your coin is simply die deterioration and possibly some split plating.
Again I learned something every time I come out here now I just got to retain it thanks I'll Merry Christmas
