it doesn't matter with the die crack or not really, I've seen so may of them that I don't even look for it anymore. it's just that common for 2008 P Arizona for the die chip over the initials. like 50 cents to maybe 3 dollars on ebay, with the die crack also. just not worth the effort, like the "snow on roofs" and "leaky buckets" of the 2015-P homestead, although if the roof is all die chips and really "snowy" it can get to a decent price.
Definietly it's a die chip, but that's what all those gimmick named quarters basically are, some die chip or chips but nothing to dramatic, just in an interesting spot.
@ Big-Kingdom, I don't look for them, they are just in the bank rolls I get. Get 8-12x face for them. yes I will keep and sell. I'm more into the W quarters, found only 2. This is what I found out about Arizona quarters.
