1926 Peace Dollar In Pga Holder Looks Weird

That coin's surface looks very . . . not good.

I can't tell if the slab is the older PGA or the newer Mexico-based PGA. Is there any chance this coin was in Louisiana in 2005-2006 or SE Texas in 2017-2018?

this is one to stay away from.

I cracked out of holder used a coin brightener MS70 and this is what the coin looks like now

AU Details, whizzed.

The scratches across the obverse rims (visible at 3 and 7-9 o'clock) and reverse rims (clearly visible at 2-3 and 6 o'clock) are the dead giveaways.

Whizzing: Mechanical Alteration to Fake Luster
Whizzing is a mechanical process used to imitate mint luster. A high-speed brush or rotary tool is applied to the surface. This forces the upper metal layer to smear. The coin may look bright at first glance, but the brightness is artificial. Whizzing destroys the microscopic structure responsible for real luster.

The surface becomes unnaturally smooth, almost melted. Under light, the reflection does not rotate. It moves in straight streaks or slides across the fields. The texture looks "liquid." High points of the design often appear softened or flattened.

Key visual signs of whizzing:

Surface looks glossy but shallow

Reflection does not form a cartwheel pattern

Raised details lose sharpness and look rounded

The entire coin has a uniform, synthetic shine

Whizzing cannot be undone. Once the metal flow lines are destroyed, the surface will never display natural luster again.

In the market, whizzed coins lose most of their collectible value. Even scarce dates are often sold at or near bullion value. The coin still contains metal, but it has lost its numismatic character.
