This coin has such major die scratches on the OBV. and REV! It also has a major "die cud" on the rev near the lower right of the Memorial. Pretty cool!
It looks like Acid Rain! Now we know what is causing the destruction of most of the Copper plated Zinc Cents! Frank
Jess Those are die polishing marks. And, FYI: A cud must include the rim. By definition a cud is a broken part of the die that includes the rim. Yours is nice, and is a die crack, plus a small internal die break. Very nice.
These are called striation marls not die polished marks striation marks run in different directions were polished marks will run in one direction mostly downward.The die crack is no big deal just a regular die crack.The die break looks like a blob and that is called an interior die break seperate from the die crack JC
I thought striation marks were caused by polished dies. Definition; Thin raised lines on the surface of a coin, caused by excessive polishing of the die.
Yes but there is a differerance in the terminolgy. Polished dies are from polishing of the die, but striation marks are from excessive polishing of the die ,to different terms ,but basically the same except striation marks run in all directions polished marks don't so they are different terminologys. I do get very technical at times but that's my nature JC
I'm just going on the definition that PCGS is giving; "Term for the incuse polish lines on the die which result in raised lines on coins. These are usually fine, parallel lines though on some coins they are swirling, still others with criss-cross lines. Planchet striations are burnishing lines not struck away by the minting process and are incuse on the coins." And polished dies; "A die that has been basined to remove clash marks or other die injury. In a positive sense, Proof dies were basined to impart mirrorlike surfaces, resulting in coins with reflective field." You decide and then make up your own definition.
Look up striation lines in different areas of the web, and then you decide what i'm talking about just a matter of different terms Rockdude. JC
These are the same thing, just used in a slightly different context or explanation! In either case they both refer to Die Polishing Lines. Die Polish lines whether thin (fine or minor), medium or heavy all create (leave) striations on the coin! I don't think that I have ever heard any experts ever refer to any Die Polish Lines as striations...except in trying to explain the effect on a coin (i.e. Die Polish Lines exhibit themselves as striations on the surface of a coin).

And I will dumb it down... It looks like a storm on the coin, with a lightning strike on the rev. No, okay I will keep my imagination to myself.:rolling:
Very Common for nearly all 1980's Lincolns. I agree with the cud statement, and that both are the same meaning used in different ways.
