Sometimes it's difficult to find a good hard strike on those early 80s pennies as many of them are blurry to begin with even in perfect condition. Supposedly the 1982 DDR001 (maybe even the one in the referenced photo) was somewhat difficult to photograph (the photographer took months to get it perfect) and could possibly be due to this. I'm definitely no expert, but I have something similar that was difficult to photograph and clearly shows doubling in the right conditions. My coin also exhibits late die stage, die fatigue characteristics, numerous zinc zits (no rot though) and maybe a rim error, further compounding already difficult photograph coin, so maybe you should take it to somebody who really knows how to photograph these things to see what you have for sure before you pop it in the
Gumball Machine... Just my 2x cents.
