Hello I was wondering if this doubling is machine doubling or actual collectible doubling. I’m pretty new and have a hard time sometimes telling the difference.
A Doubled Die is considered a Variety. Mechanical Doubling, Machine Doubling and Die Deterioration Doubling is considered worthless doubling and nothing to do with a true Doubled Die Variety.

Yours is a proof nickel. Did you try to compare it to one of these? https://www2.briansvarietycoins.com/listings/cat/42
