Re: Morgan dollar die information

Thanks! Will keep trying.

RE: The sample page. Notice that for 1896 were were 4 obverse and 2 reverse proof dies used. How does that compare with accepted varieties? There were also 48 obv & rev dies from the Philadelphia Mint. Can those match known varieties?

Re: Lack of posting topics and overall interest

Keilg1 - it's also about communicating ideas to increase engagement and improve what is already present. VAMpires can easily use this forum to offer suggestion and then discuss their merits, constraints and implementation. Everyone was once a beginner -- a trite but true statement -- what attracted ...

Morgan dollar die information

In checking through Record Group 104 Entry 6 at the archives it appears that these volumes are good sources for die information. This includes quantities and control numbers of dies sent and dates sent, dies used, dies destroyed and proof coin dies. There is nothing about pieces struck from each pai...

Re: Lack of posting topics and overall interest

My comment was more generic than specific. As an outsider to VAMs, I see so much knowledge, information, skills and possibility among experienced members. Yet, together almost nothing is done to understand and respond to potential new enthusiasts....or to capture and stimulate those who venture to t...

Re: Lack of posting topics and overall interest

Rather than pointing fingers of blame at one another, try working together to simplify the "VAM experience" and improving response to potential new members? Use your collective knowledge to prepare and market (not 'sell') materials and options that will interest new collectors, and respond to their ...

Re: Is there a trick to photographing overstruck coins to make the original more visible?

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

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

Re: Best resource for satin and matte low relief peace dollar proof diagnostics?

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...

Re: Best resource for satin and matte low relief peace dollar proof diagnostics?

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: Milk Spot Question

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...

Re: Milk Spot Question

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.

Re: Proof vs biz reeding

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.

Re: Proof vs biz reeding

"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...

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.)

Re: Proof vs biz reeding

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...
