I'm good with that, and I'll join you for that beer!
The deposition is fairly slow, so the grain structure is very fine. Too fast, and larger grains form, which compromises the reflectivity.
Wow, the lengths you will go to not admit you are wrong are impressive.
Sorry, but there are no flow lines on a mirror. There is microscopic grain structure, but not flow lines. There are polish marks on the glass, but...
Well, not exactly. You jumped off the deep end with your mirror comments: "The quality of the image you see in the mirror is due to the high...
Hmm, I agree with a lot of what you said. I think we're getting somewhere! I don't see much point in arguing about proofs vs business strikes, but...
I think the OP's question has been answered. A worn die of course produces Mint State coins. How could it be otherwise? The luster discussion is...
Here's an animated example of a lustrous coin based on my definition of luster. Note the coin is a business strike, with no mirrors, and is MDS....
I said nothing of the sort. What I did say is that the discussions that dispute my understanding were wrong. I agree, but I was simply...
Please use logic. If you say Doug is using the widely accepted definition, and mine is different than Doug's, then you are saying mine is not the...
What they are saying is that luster is used to gauge business strike eye appeal, while reflectivity is used to gauge proof eye appeal. They are...
I did a quick search to see what resources there were regarding numismatic luster. Here are a few:...
I think you are correct, and I've been quite gentle in my admonitions since I have a high level of respect for GDJMSP. However, I don't agree that...
Actually, later die state coins generally do have more luster, and terminal die states the very most. But it seems your opinions have been formed...
Sometimes common sense is not enough to understand and explain what is happening. It is true that luster is created by metal flow, but in a more...
I actually like that idea a lot, but it would for sure be confusing.
Show me the discussions. Because they are wrong.
Late MDS / early LDS dies get the highest grades. This is because new dies don't produce much luster, and luster is the most important quality in...
Numismatist. I specialize in Lincoln Cent Die varieties, their study, and photographic analysis.
I'd expect a pre-made roll to be made by machine, and if so, there would be a patent application for that machine. I have not seen such a...
