1964 Washington Quarter Die Crack

Highly unusual for a die to crack in that manner? The line appears to be concentric. Is the line raised or incuse? If incuse, it's more likely PMD from a rolling machine. I'm still learning so this is just my humble opinion. Waiting for the pros to offer their opinions.

The truncation of Washington's bust is a point of inherent weakness in the die design, you will see a similar crack repeated throughout the years on Washington quarters. The leading edges of the eagle wings are another point of inherent weakness with repeated cracks. This crack is a bit larger than usually seen but I have seen others that extend towards IGWT and up across the pony tail.

At first I thought it was PMD but upon closer inspection with a 10X loupe I saw the line was raised from the tip of the right leg of the are to George's bust and across the bottom and then extending upward out into the field to his right and ending where the red arrow is pointing. The photo does not show it as clearly as it is when in hand. I doubt it has any sort of premium as an error but it is different and I'll keep one of them as a conversation piece.

A scratch will be raised, next to an indented groove.
