I have one that looks very similar, except the entire date is missing as well as a very faint s that I can only see if I tilt the penny and eye it with a flashlight ( very faint to read...I'm almost...positive it's a 95..i haven't gotten a magnify glass to it just yet), the L looks almost doubled right now the I & B is just as faint as the date..the B a little better to read, and the Y is fading. From what I can see with the naked eye the I, G, O, R & U are almost gone in " In God We Trust ".
Good example of a debris fill die. USMC60 PS If you're going to call it a grease fill die, please tell me what kind of grease was in the die.And show me an example of that grease.https: //www.cointalk.com/posts/2698669/ This thread has a good example of debris that can be left on the die. Or would you consider the first photo which is definitely a form of grease that remains on the die I doubt it.
http://www.cointalk.com/posts/2698669/ Just like in my thread. I can only go by what I visually see in the photo. I basically see copper and nickel shavings, cannot quite make out bonding agent that holds them together. Maybe one day when I'm rich I'll send the sample into the lab to find out exactly what's in the debris.
I think the term 'grease' is used instead of "machinery oil'. Kinda like 'clipped planchet' instead of 'incomplete planchet'
