Technical question on whizzing

satootoko

"Whizzed" usually means cleaned with a rotary wire brush, but is there another term for the way this one was cleaned?

That one might look "whizzed on" but at least we get to get another peek at your signature coins!!!!

"Worn" works for me.

That could actually be toning, in a "woodgrain" pattern.

May not have been cleaned or wizzed, just oddly toned:

How about "Buffed"? I always think of a whizzed coin looking like a buff job on your car. A whizzed coin has this "fake" luster to it and you can see the swirl marks in the coin when the coin is held up into the light at the right angle. Whizzed = Dremel

I have to agree with lordmarcovan, that looks very much like woodgrain toning.

I have several coins like that in AU or UNC which have simply toned in that pattern.

You can also get lines like that when a coin is struck. They are usually not so visible though until the coin begins to tone and then the striations really show up.

I wanted to say what GDJMSP just said; I've seen that in the alloy of a coin which is sometimes not properly mixed.

I can't understand what would cause that kind of tarnish pattern, and wilth all due respect to Doug and the Jester, I don't see anything like polish lines in the coin. I would not expect die polishing to put lines across both the fields and raised areas, like a wire brush could.

But, no matter where those lines came from, that coin will not be filling the hole in my 5 sen collection!

GDJMSP

Well they're not polish lines really - they are lines formed when the metal flows as the coin is struck. In the case I am describing there are no incuse or raised lines - but you can see the lines nonetheless. It's more like an effect of color than anything else. I own a couple of gold coins with this effect and they are graded as MS65. Not that the grade has anything to do with it except to confirmm they are not cleaned or whizzed.

The coin you are asking about Roy may be an example of what I describe or it may not. Only in hand examination will tell you for sure.

There are a lot of examples of streaky British bronze pieces in the middle years of George V, especially 1919-1922. I have never cared for that look personally.

Of course not! It's a five rin piece.





I have some coins with this kind of toning. I actually like it.

Could be an improper alloy mix too, just seemed a little too streaky to me for that. Ones I've had, including an American flying eagle cent, were more blob like.
