This is an 1973 5c ICCS MS64 with a close-up picture of the back of the Queen's head.

Hello kuh_85.. It almost looks like Struck Through Grease but...not sure...hard to tell sometimes showing the whole coin leads to a clearer picture of what's going on (no pun intended) ..nice closeup though.

Hopefully someone can pass along their expertise.

Also, is it wishful thinking or is there some doubling along the hair?

That's a nice shape coin...does look like a bit of doubling going on with the hair line... that is a neat find...hope someone with more experience with what that spot might be can help out.

That area behind the hair looks like 'waves out upon the ocean'*, as photographed from high altitude.
I would think that may have been caused by a small droplet of oil, between die and planchet.

I don't think it's a strike through. This area shows that effect on more than one date and at different intensity. I suspect it's a stress area that bends/ripples slightly the surface of the die, resulting in a "sun ray" effect radiating, as can be seen on many other denominations. Nickel 50 cents often present that effect.

I did think of that as I have a couple of 'Glowing' examples (1938 & 1997) but this didn't seem to have the strong, radial line effect that those have.

I do not know the cause but I have seen the same thing on many different pure nickels.
