PSD Or Worn Die 1991 Dime

Looks like it was Struck Through Grease to me.

I have a Struck Through Grease nickel that reads "five c nts"

I am curious on if Struck Through Grease coins have value as well?

Not really until a very high percentage gets blocked out. Way to tell if it is a Struck Through Grease issue? Note the affected devices (even DIME) shows widening of the devices. This is cause then the deepest part of those devices were partially filled and now the devices look wider. Wider? The devices on a coin are tapered in shape. Narrow at the top and wide at the bottoms. So when the narrow part of the device get filled, only the wider part will form. on 'US U' on the EPU, show a almost complete will with grease in the die. All you see is the outline of these devices. Note the 'N' on UNUM and the 'M', the 'N' is a lot wider and the 'M' is showing the normal device. (tapered at the top and widened near the field. Although there is no premium for this (because it is common) knowing what it is a good thing. People do sell these to the untrained new collectors. They end up buying it and find out later they were scammed.

Your tastes will probably evolve. One day you might only want to keep ones that have completely removed devices, some alter the meaning of a word or phrase ( In God We Rust) for example. There is a market for the interesting ones and it's ok as long as they are not misrepresented. Some are just so neat they are desireable - see my signature below. DDO's RPM's Die Cracks, Greaser etc. are bought and sold legitimately everyday.
Here's a picture of my avatar. It's a Greaser. It brought a nice premium or I wouldn't have sold it. The person I sold it to knew what it was and liked it. That's the same reason DDO's are sold.
