Kind of looks like a true doubled die.

What markers are you looking for on the reverse side of the coin?

I sincerely appreciate you taking a look at these pictures!

Upon further review, the doubling appears to be flat. My guess is this coin would be graded as a Machine Doubling, and not a True Double Die.

Can anyone on here confirm my suspicions?

Your Mercury dime has a DDO error, which is fairly common among 1940 dates, it add a small minimum value. Good luck!

Silver77 is correct, the coin shows strong Machine Doubling damage, not a DDO.

This is Machine Doubling. Note how flat it is? It also reduced the original size of the devices.

It is also in great shape. So many of these are worn very smooth, and you have a ton of detail left. This is a great find, regardless of its monetary value.

This coin exhibits very classic Class II, Distorted Hub Doubling.

Class II (Distorted Hub Doubling): is a misalignment event relating to either the Die or the Hub, which has expanded or contracted too much in relation to the first hubbing during the annealing or tempering processes. This is considered an error, and MS examples are worth a premium.

Mechanical Doubling is not the result of the design on the die being doubled. Rather, this type of doubling occurs when the die strikes a planchet. If the die is not properly seated, it can move slightly or bounce during the moment of striking, creating a flat, shelf-like doubling. Machine Doubling is considered damage and results in negative premium.

Where are you seeing the doubling from the Class II hubbing? The date and the Y are definitely MDD, the E in W and the S in TRUST might be showing some hub distortion, but I'm not convinced.

Condor101 is correct.
This is classic Machine Doubling on the obverse, nothing about the reverse.
