Lessons in problem coins: Whizzed.

It's been whizzed. If you replace the wire brush with a softer, yet still abrasive material, you still move metal, and you still get the false luster effect of whizzing, where the fine lines that were created pick up that liquid, fake luster look.

Nah, that's not being mysterious enough for a god-like creature like Doug. Deities often speak in riddles and parables.

 

The arc shaped pattern displayed in the fields on the OPs coin are distinctive and characteristic of whizzing. The coin was affected by a high speed rotor - arguing the semantics of whether it was a bristle or softer head seems a bit silly. I think it is perfectly accurate to describe this coin as whizzed. And you know me, I am a stickler for using the right word for the right thing when it is important.

 

Exactly what I thought. Still waiting for Doug to come along and tell us why it's not whizzed.

Where's the popcorn emoticon here?

 

Not an emoticon, but...



So to review the bidding, so far all we have is, "It's not whizzed because here's a bunch of pictures, COMPLETELY UNRELATED TO ANYTHING AT HAND, that other people have called 'whizzed' but weren't." Do I have that about right?

 

^^ I was tempted to like that, but then I just don't need to be traumatized seeing how many likes he's gotten. (lol)

 

Glasswool was the favorite buffing medium in my experience. Wire displaces too much metal.

 

Whizzed Lincoln cent:

 

There are various toughnesses of nylon bristle to consider as well. Wire is so last century.

 

This thread has gone in a different direction but knowingly selling “mechanically or chemically altered” coins with the intent to deceive is against the ANA’s bylaws and could theoretically lead to discipline or expulsion. I have no knowledge how often, if ever, this law is enforced.

 

Good informative thread.

 

+1.
We may not all agree 100%, but discussions on doctored coins, deceptive problem coins, altered coins, etc. , are a good part of the value of CT.
Of course, it's just fun to interact with other coin nuts also.

Since we are picking a few nits here...let me comment that metals or alloys do not have molecular structure. They can have crystalline structure and exist mostly in a matrix sometimes called the "Sea of Electrons"

Now after picking that nit, the OP coin (to my admittedly untrained eyes) just looks like it has been buffed to within an inch of its life.

 

The REASON I disagree with you is that I believe the fields of that coin have the telltale quasi-luster lines indicative of whizzing. The FIRST (not only) thing to look at is whether the luster "cartwheeling" acts as natural luster would or just a weird facsimile of it. Of course, NEITHER of us has it in the hand to do a PROPER examination of it and all we have are still photos, always a bad substitute. But I am convinced that someone has imparted quasi-flowlines onto those fields, and that makes it whizzing.

Now, was there a SECOND step, to tone down the whizzing with some light field polishing? Maybe, and if that's your point, we actually agree. But whizzing IS in that coin's past.

 

So which is it? Polished or buffed? And why?

 

COming from a fellow that has put lots of car parts on a buffing wheel but never a coin..... The coin @C-B-D posted had exactly the appearance of an encounter with a buffing wheel to my eyes.

 

Plot twist: it's a proof. Those are die polish lines

 

What is a car part buffing wheel made of?
