1984 Nickel- Struck Through Grease Or PMD?

I might have answered my own question, because it defintely looks thinner than other nickels. Still if someone agrees or thinks otherwise let me know.

I am undecided because the rim on both sides looks so pure. But, you say it appears thinner than others. Getting the weight of it to 1/10 gram at least (1/100 is better) will help to decide this.

For all practical purposes, it looks struck through heavy grease on both sides (and should be normal weight). A Dryer Coin would show other effects, especially concerning the rim, that are not present here.

I'll weigh it when I get home. In the picture the rim looks strong but I actually thought it was kind of rounded off and a little weak. The lens on my camera phone is broken so maybe I can take another picture with a different phone later.

In any case of a coin being "struck-through", the weight should be normal (unless it retained debris). A normal nickel should weigh 5.0g.

If you can, an edge comparison pic of it next to a normal nickel would help to show how thin it is. Also, other than being thinner, how does the diameter compare to a normal coin?

Upon closer inspection, it may just be a Dryer Coin, but other possibilities need to be excluded, because that would be a desirable strike-through if that's what it is.
