Saw a Bailly trade dollar pattern, J-1315, on eBay (see URL). At first, thought it was just worn and abused. Closer inspection makes me think...
Do the grandkids actually have an interest in coins? If not, some other gift, even cash, might be better. If they have no interest in coins and...
Thanks for the info.
Anyone know if portable XRF (xray fluorescence) units can analyze a coin in a slab. I imagine large bench units have the range, but what about...
I think we're pretty much in agreement about the definition of a hub. I'm not so sure dies could not have been created from hubs before the 19th...
So, even the mint mark has to be there to fit your definition of a hub? Cal
Yup, you're right Doug. Reminds me of before I retired from biomedical research and would go to scientific meetings. Presenters would show a...
Still, a hub is a hub, whether used by a mint or a forger. I doubt the forger came up with the idea of a hub on his own. I think we still don't...
Thank you very much for that info. I'm curious if there are good articles or books on the technical aspects of early U.S. coinage. I'd like to...
You could be right. I don't know enough about metal engraving to know how hard it would be to produce flat fields on a hub. Personally, I could...
I have to root for small collectors getting first choice even if fewer coins are ultimately sold. Still think if the lottery were setup right, it...
I don't know what was actually done in the U.S. mint, but initially creating a master hub might have some advantages over initially creating a...
Under the plan I mentioned, for those lottery winners who didn't buy within a week, then the next households down on the list would get an email...
If the mint was really concerned about equitable distribution of a limited mintage, they could have a pre-sale lottery. A month in advance of...
The twirling lights on the one but not the other make it hard to compare. Cal
I've always assumed that all copper will windup brown eventually unless it's coated to prevent reaction with gases. Apparently, it can take many...
The standards of two Roman legions? ;) Cal
I've always been amazed that they turned all 10 over to the mint for authentication. I would have expected one would have been submitted after...
No acetone won't hurt metal coins. Search forums for acetone, and you'll find more than you want to know. Be sure to read precautions regarding...
I tried a LED ring light, but was never satisfied. Sometimes there would be reflected images of individual LEDs; other times, using a diffuser,...
