I was recently looking through some coins and I noticed this 1994 D Penny. I noticed that the "I and the N" are very long and the "U" in Trust is also. Also, in liberty the "L" looks like a upside down slanted "T". The "W" in WE also looks like its an error as well. Here's a few pictures.
This coin was struck by a very old and worn die pair. This is characterized by lettering "drawing" towards the edges as seen here; that metal has literally been worn off the dies by the hundreds of thousands of coins they've struck. This is a pretty late die state. Not valuable, but of interest to the true coin geek because of the advanced age the dies were able to reach.
