No it is not an alright way to do it.
Why ? Because to some people toning is damage. They don't understand that all coins tone eventually. They don't even understand that most of the...
Slider - Your comments are a perfect example of an issue that I have often talked about. That is the improper use, improper use in my opinion...
If they have I can't see it.
And no it's not the ANACS slabs themselves causing the toning either. Toning is kind of a hit & miss proposition, some coins just tone faster than...
I have a copy of an article written by Lantz on the subject. Those who want to read it, send me a PM with your email address and I'll send it you....
Fair enough. Contact marks on planchets can occur during the annealing process. But even so, that is still just 1 of the dozens of ways that a...
I'd say your both right. Yes there were Treasury releases in the '50s & '60s. But all of the GSA sales took place in the '70s. edit - and keemao,...
Yes, they do anneal cent planchets. Left over copper particles inside the furnace are what cause sintered planchets. And 19Lyds - the conveyor...
The Grey Sheet is a thousand times more accurate than the Blue Book. I don't even know why they bother to print the Blue Book. It hasn't ever been...
Mathew the annealing process does not begin until the coins enter the furnace. And it ends the moment they leave the furnace. Anything that...
I stand corrected.
No, I was not wrong. Do you think that the US Mint is the only one that uses the same processes ? Most of the mints in the world follow the same...
Think for a minute, use your head. They want the planchets to all reach the same temperature. If they were piled on top of one another in drum...
Those are annual mint sets issued by the French mint from 1964 to 1997. The mintage I have listed in Gadoury (the French version of the Red Book)...
You're kind of mixing things up here now. Your original question was if chatter could be caused by the annealing process. And that answer to that...
Yeah they got tumbled around, but not until after they came out of the annealing furnace.
And John, metal flow does not cause or create any chatter on the coin. Metal flow usually removes all chatter that is on the planchet. And yes,...
Annealing does not cause or put any marks on the planchets - none. When planchets are annealed they are laying flat on a conveyor belt, that belt...
Not that it matters, but I'd bet there are over a hundred threads discussing the same question.
