My experience with metal processing is minimal. What we need here is Lehigh.
If annealing does nothing, then why do it? Also, you said "most of the crystallization". How much does it take to affect the toning process?
There is absolutely nothing said there that I disagree with. There is also nothing there that says it is the shows money. I am positive they...
I would be willing to bet you are wrong with one caveat - some of those scenes are setups.
You don't need closer, you need stiller. Your picture is big enough to tell, but it is too blurry/out of focus. As for your picture, look here;...
Just guessing, but I would say that it is not your camera that is the problem, but the operator. It is really hard to hold a camera still enough...
OMG! You mean we might actually have a chance of doing something? Really? May I assume that you mentioned eBay?
You are making an assumption that may or may not be valid - that all silver sheets undergo the same annealing process. I could easily see a...
Annealing changes the crystalline structure of the metal. That will absolutely affect the tonability (if that is a word) of the coin. However,...
MPL's are not my thing, but I have picked up a bit around here. They are supposed to have square rims. Notice the GSC coin. Those rims look...
In hand, I am 99% sure that is a strike through. I see zero evidence to indicate a scratch. It has a square end (south) and, it is hard to pick...
Best of my recollection, there was an "S" on it and the expert said it was not Paquet. That leaves "a 61S then it would be equal to the finest...
It does look like there is something going on there in my original pic. I cannot see it in hand and here is another picture that agrees with my...
I don't know. The darkening is much more obvious than any displacement of metal. I cannot make out if is is just a darkening or if there is...
1916- PCGS slabbed I hope to get this done before I leave, but I will have to short cycle it. I will be gone for about 10 days starting this...
1915-D NGC slabbed I hope to get this done before I leave, but I will have to short cycle it. I will be gone for about 10 days starting this...
A couple newbies and we finally have a leader - ddoomm1 again. Top 10. Columns are rank, name, average, and number of guesses. ddoomm1 0.407...
This is the most consistent I have seen the vote. 70% went for 64. Problem is that PCGS said it was 63. In hand, luster is not its strong suit....
Another wood grain that I don't know what to say about. I would probably go 64 in hand, but those spots are kind of annoying. However, there are...
Welcome to CT. Stick around and enjoy. As for the 1959-D wheat, see http://www.scvhistory.com/scvhistory/signal/coins/sg090206-coins.htm.
