Is this PMD not sure what is in the lower part of the 8. If you look on the reverse there is a spot where the 8 is.

It's a filled die break. Some of the oldtimers call it a "plugged die". I have the same year (1983) with that break. They might have been struck by the same die. The spot on the reverse is just a coincidence. Don't look too hard. You might see some camels running through the mirage. Chris
Whenever I see someone rely on coincidence I am reminded of a quote, which I believe was attributed to anonymous, ; coincidence is nothing but a lame excuse for the intellectually lazy! There, your humor for the day
