https://kb.osu.edu/dspace/bitstream/1811/3687/1/V49N02_073.pdf Is a good article on ancient gold purity. It shows that Romans were able to...
I will research it and get back to you Doug. The main point is it becomes the increasing difficulty in extracting the trace metals that naturally...
It was just an idea, the standards could be adjusted. Its not like we can do anything about the situation anyway. I would just like, if I were...
I was referring to collectors buying up moderns and sending in for grading. If it didn't get 70 they would either resubmit or sell the coin off....
I think its a trap too many times we fall into trying to calculate "investment value" of a purchase. I do it too, trying to rationalize a $1,000...
Besides Tye and Mitchiner OCV-NISWC, what books would cover these Doug?
The OP saw the coin in person at the ANA and negotiated the price there. He was just asking opinions here. I agree its better to know about the...
Well, I could be wrong, but I thought the sources had trace elements in the silver that passed through to the coin. A cc was primarily coined from...
But when you have 40% of a mintage 70, how is it special anymore? If there were business strike 70's they should be exceedingly rare. By...
Ok, I will research it. I know the US didn't have any kind of capability like that for most of its history. You say that .9999 is doable for the...
Which is why they shouldn't be judged the same. I think a hard break at a certain date, 1965, 1970, whatever, and everyone knows what is modern...
Good information. I would not think the machinery nowadays would be the limiting factor, not the metal composition, (though in analysis the trace...
I need to look at these more at better shows and dealers. Most I have ever seen were junk, those look nice. Hmmmm, whether to start ANOTHER sub...
Thanks Doug, I was wrong too of course. I am not an expert, though, of modern AT and how to tell. I just thought if one of these experts here...
Yes, yes I do. Older coins used to be scarce in 65, and rare in 66 on up. They were special. What is so wrong with a 63 being an above average...
Well sometimes mine go for an accidental ride in the washer, so I am helping out my fellow citizens. :) Um, yeah, I always wash my hands after...
Well, I would wager most circulation coins are cleaner than your hands are. Paper money, now that is nasty. Nickel is a very clean metal, and...
If TPGers truly want to slab modern coins, (and they do, for the cash), then maybe their should be a break, maybe 1964, of grades. Modern coins...
Yep, which is what you should do now anyway. So that leads to the argument what is the purpose of the slab grade at all then? What are you paying...
20x is a good idea, how about something like 100x or 200x flawless being graded 70. Or how about the idea that TPGers originally promised and not...
