i have seen a lot of what I understand to be "greased coins" having a number or letter either mostly or completely missing. First question am I using the correct terminology and second are they worth keeping or do they have no real value. I am out of town or I would post a picture. Be back later today. Just curious.
First, the correct term is "grease-filled die". It is the grease and minute debris that continues to fill and harden in the recesses of a die from continued striking that cause some of the letters and/or numbers on a coin to, seemingly, disappear. Some people like to collect them, but they are so common that they really don't add much of a premium to the value of a coin. Chris

I got good eyesight, lol. As for @paddyman98, he digs these things up. He's isn't the inventor, he's the digger-upper.
@SuperDave @eddiespin I spend a lot of time searching for charts, diagrams and webpages dedicated to errors and varieties.. I love this stuff! But It's important to always say "I want to share this image or webpage with you" when posting answers for anyone. I love charts! Here is some examples I want to share with you, Not my images
