The side of the N has been smashed to nearly touching the U. There's as much space between those two letters as there is between the first U and the N, on an undamaged coin. The only way that could be a "2" is if a "2" was punched into the die instead of an N. I'm not seeing that happening.
Sure! It's rotated 90 degrees CW and the base and diagonal are about twice as thick as the curve of the top. Have you ever seen a font used for coins like that? I sure haven't! This reminds me of the days back in the 60's when everyone hung around with Timothy Leary. Chris
Another thing to consider would be the size of the supposed 2.. Much smaller than the original numerals used on the Obverse size date.
I didn't say it was a 2, just agreed that it looks like it. The first couple responses said they didn't see it which I didn't quite understand. I don't know why anyone would look so closely at a '72 Lincoln in the first place. I would absolutely vote against wasting any money on grading.
I'm sorry, people who use English as their first language understand that saying something "looks like" something is not the same as saying it is that thing. I've also stated in the past that the brain is always looking for familiar patterns whether they're there or not. The phenomenon is called pareidolia. That's part of the reason I wouldn't use a microscope to look at a coin.
