Re: Did those attending ANA find it a good experience?

Helpful comments. Regarding WiFi: We are nearly a quarter-century into the new millennium. WiFi is cheap and easy to deploy. There really is absolutely no excuse for large shows not to provide it to the dealers and guests. And the ANA is not the only show where this is an issue. Dealers should not n...

Re: Did those attending ANA find it a good experience?

Nice the several good coins were found, but I was thinking more of the total experience of attending -- what worked, what didn't, what could have been better.

Did those attending ANA find it a good experience?

I'm curious about how those who attended ANA felt about the experience. Are their aspects open to improvement?Are some parts "just right?"

Re: 1897-P VAM-11 Doubled 1-97, tripled 8. Misaligned Die Need help on minting process, die adjustments, possible recutt

To be straight forward, I read too many assumptions to untangle. Suggest going to From Mine to Mint and examining the toggle press descriptions and images. Then try Journal of Numismatic Research (JNR) Issue #1 with an article about a toggle press patent and drawings. Follow them carefully and you s...

Re: How accurate is the population counts?

The "populations" for all the major authentication companies report only the coins received AND graded by that company alone. Also, the tables do not include any coins deemed not gradable, or not accepted. Thus, for all except a tiny minority of date/mint/denomination combinations, "population repor...

Re: can an AU55 coin be PROOF LIKE

Proof-like is a description of the relative mirror-like reflectivity of a coin's fields. It is NOT part of the "grade" or condition of a coin

Book - "From Mine to Mint, Vol 2"

One of my current tasks is the successor book to From Mine to Mint . This continues the kind of process and mechanical approach to minting coins begun with the first volume. That is, the emphasis is on how equipment worked, how it was used, and the effects on coinage - including errors and defects. ...

Re: peculiar 21d reed queation

Good illustration of how the upper die surface was cut to help guide a planchet to the center of the collar. In addition the reeded part of the collar was slightly wider at this top face than the bottom. So... there were two interesting aspects to collars: 1) they had a sloping guide cut into the to...

Re: peculiar 21d reed queation

It would likely be helpful to new and some seasoned collectors if the terminology could be better explained in the background info sections. The section in FMTM describes how reeds were cut into collars. Also, some presses used circular openings into which collars with various opening sizes were ins...

Re: What is the correct term?

I would add that this is atypical, so calling it 'atypical die erosion' would likely be correct. This particular obverse apparently either wasn't or couldn't be properly hardened. It's a great story and it's reverse mate has a story of its own worth exploring. Good explanation. The photo shows turb...

Re: 1923-S Super collar

If the reeding is otherwise normal (coin struck fully in collar) and there's additional reeding on the rim, it would be a collar clash, where the hammer die hit the collar die before striking this coin. In the "die profile," below, you're saying the peripheral face (rim) struck the upper surface of...
