I don't know anything about pennies but the double ?die/stamp? on the date and mint is awesome. I like the uniform look of it.
It is very cool looking, but notice 1) everything is in the same direction 2) the lower figures appear very flat and shaved off. This (I think) is characteristic of strike doubling, or machine doubling. Assume you are cutting out a cookie and the cookie cutter moves as you bring it up. Don't trust me, I am sure others will chime in.
@The Bob I am new to the site too but stick around, everyone is very friendly and helpful here! Usually no one will insult a coin and they are very kind if they need to inform you about its condition or authenticity! I had a 1882 morgan cc I found out was fake but everyone was very nice about helping me ha
Yes, this is ejection doubling, aka die chatter. The coin did not eject clearly from the press. Double dies will show doubling with some separation, which is best seen at serifs and the ends of letters. This doubling looks more like a shadow than another presence. The 1955 cent is the best and most dramatic example.
This 70-S cent close-up photo is a great example to show as ejection/mechancial doubling. There is no separation of the digits in the doubling, and the doubling is flatter, and not raised off the surface of the coin like the main date.
