You need to use a 3D optical profilometer, not a regular camera.

Nice ones start at about $50,000 and go up from there.

Keyence 3D profilometer

There is no such thing as a "Zerbe 1921 proof." All the ones given that "title" are proof-like, made on a normal toggle press. I have not had the opportunity to carefully examine a "Chapman proof," although I saw one in an NGC display a few years ago. These coins were described as "not proof, but ev...

Several TPGs have a tendency to "coinfuse" or ignore facts when it comes to satin and sandblast proofs. Several ordinary strikes have been certifies as "proof" because they were sandblasted -- even though they lack required detail and/or mechanical indicators. The coin in question is nice but the re...

RE: "It's frustrating to watch investments go to crap because of some incompetent goings on at the mint..." Your frustration is reasonable and well understood. It's disappointing to open the bank box and find spots on gold and silver pieces that we thought were well protected. I have no empirical d...

RE: "It's sad that Mercantii and the boys did not take this lesson from George Morgan, but I guess they are too busy writing books and selling signatures for some TPG labels to care about stuff like that." Planchet preparation was done by the Coining Dept, not Engraving. So those referred to were no...

Thanks JB. It's strange that they were perfect until I changed them to their present holders. Scientific research into this was done more than 10 years ago and published. Alloy mixing has no bearing on spots. Surface spots are nearly always the result of airborne contamination. Each time a planchet...

Leave stuff in the ORIGINAL capsules (if any). Every exposure to air greatly increases the opportunity for spotting of all types. How to get rid of this has been mentioned many times. Check older posts.

Collars were very durable - far more than dies and many other parts. But when they cracked or broke, they immediately fell apart. Therefore, the box of junk you saw. This stuff was usually sold to steel scrap dealers although counterfeiters might have bought them to copy authentic reeding.

Missed my point but whatever, I'm out.

Seemed quite clear to me.... Did not intend to step on any toes.

"There's nothing about reeding." This is a pervasive loss of information, only exacerbated by TPG holders. There are several mysteries in reeded edge coins, and suspected varieties in lettered edge gold, but we don't have access to enough data to ask the right questions. There is also the anti-coun...

That might be the incident I was thinking of... then there was W. Barber send out DE dies without dates in 1876.

RE: "Yeah, whatever it is, it's definitely funky, interesting and mysterious. I don't recall seeing anything like that anywhere else aside from the similarity to the acid treated reverses. Maybe one day @RogerB will surface some sort of correspondence regarding it." Additional San Francisco Mint doc...

Proof Morgan’s were struck on a screw press in the medal room.

A hydraulic medal press was used after 1893. (The screw press specifications will be in M2M-2 -- once I finish editing and get it printed.)

... and it’ a “dry” read ( no offense ;) ) No offense taken. :) From Mine to Mint (and the successor Mine to Mint 2) were prepared to give collectors clear, accurate and understandable information about mechanical and operational processes at US Mints. They were deliberately written without flowers...

how is this question not clear? Your question is too ambiguous to give a useful response. What years do you refer to? Screwpress or hydraulic press? Which mints for comparison and what years for them? If you understood how, where and when reeded collars were produced, your question would be differe...

Please go to the book From Mine to Mint for descriptions and illustrations of how collars with reeding were made. Once you have this information, try forming a clearer question.

That's a lot of candles on the cake!

Boxes 39 and 40 (coming soon) should cover the 1859-1860 issues.... These have never been available before, so there might be all sorts of stories amid the routine scribbles.

The following volumes have been added to NNP's available documents. These cover the New Orleans Mint from Jan 1839 to Dec 1858. Go to Entry 11 and click the appropriate year. (Sorry, no Morgan dollars....) RG104 E-11 Box 29 Jan 5 1839 - Sept 11 1841.pdf RG104 E-11 Box 30 Sept 17 1841 - Dec 12 1843.p...

Hmmm.... Same things happened in this thread....or was this a quantum superposition ?
