AT or NT? Technical Grade? Eye Appeal?

AT 63,......just a stab

Looks NT though I have seen NGC body bag similar coins...MS65....the toning might be worth a small premium but that type of color won't pull in the big bucks.

Definitely naturally toned; pullaway effect at the lower left stars and date helps to confirm this. The bright yellow in the recesses makes me think it could be 2nd cycle color; but at the left rim the blue is lightening rather than going green, so it is probably first cycle color leading to cobalt blue at the rims. A little hard to say on this one; I could almost see it either way.

The surfaces look nice; I don't grade from images, but looks 65+ from images. (You can at least see that the reverse is very clean, but I can't judge the technical merits of the toned obverse from an image.) The toning is nice but not the sort that brings big premiums. Still, I like it, and the '96-P is a little bit better date as a toner than the usual dates.

Can you explain the visual characteristics and physics of the "pullaway effect" ... and explain why that absolutely confirms NT? THanks!

The pullaway effect is often seen on NT Morgans at the stars and date. It appears as an untoned "shadow" on the outer side (the rim side) of some of these raised devices near the rim. It is the result of the extreme metal flow during striking. The metal flow lines progress radially outward. My theory is that in some of these areas, on the radially outward side of the raised devices (stars or date digits) near the rim, the flow is great enough to cause metallurgical chages at the surface - either different microcrystalline structure due to work hardening, or perhaps some thin coating of surface oxidation due to the metal heating up from stress/flow, and the locally hot surface therefore being a bit reactive off the dies. This creates a very local area of surface protection, an area less able to tone. In any case, what we see is that if the coin is then subjected to a long, slow natural toning process, these affected areas do not tone, creating an untoned halo or shadow, usually on the rim side of the stars/digits.

However, if the coin is artificially toned with heat or chemicals, i.e. in a very accelerated fashion in a more reactive environment, the toning process is sufficiently strong and reactive to overcome whatever that surface protection mechanism is in these limited local areas. Thus, an oven-baked coin will toned uniformly all over, and will not show the pullaway effect, whereas if the same coin had been allowed to tone naturally for a period of many years, those protected areas would have remained untoned.

This is all conjecture, but it is what I believe to be the case after seeing many NT and AT toners.

Best,
Sunnywood

I feel this coin is NT and 64 shot 65 if the tone isn't hiding anything.

The tarnish is crappy..... could be AT.... I basically agree with Sunnywood... from the pictures, a cautious 64/65.... Cheers, RickO

Thanks for that!

Thanks ALL for your opinions and expertise... much appreciated!

If this were NT and a 65 what kind of premium would it bring? What kind of money should this sell for?

Thanks...

I think if I auctioned it off on a site like Ebay I would expect it to pull between $225 and $250 if it's an NGC MS65.
