Other than someone who paid a ton of stupid money for an ASE, who would use the service? They are as common as dirt and most people would just...
Salt spray from da ocean. IIRC, they say it can be detected as far as 50 miles inland. I can't imagine that it would react with silver even if it...
I posted a pic of a 1998 coin with issues, so it's hard to say when it started; probably has always been there. I did note in the past that there...
Do you have a link to the Weimer discussion? Nevermind, I found it. Actually it's Weimar White and not W. Wiemar. I assume if the chloride comes...
You may not care, but apparently many others do. I don't slab bullion either [nor do I plan to stack it]. BTW, how many folks who talked about...
I asked simply because I have heard from a number of people about how nice the 2014 and 2015 coins were and I was wondering if perhaps the Mint...
Does anyone know if spotting has been an issue with the 2014 and 2015 regular issue bullion coins?
Kinda cloudy n gloomy here, but we do need the rain. Otherwise it is a fine day. Regardless of what the spot material is, it is not added after...
How common is spotting on silver rounds?
That should be easy enough to prove or disprove.
The serious numismatist will simply find unspotted coins. He did mention the use of borax which does not seem to be a contaminant on ASEs.
Has it been established chemically that those spots are different than spots on ASEs or modern silver coins?
It's hardly relevant to ASEs. The spotting isn't due to detergent/s.
You may find the linked video interesting. [MEDIA]
Looks like I spoke too soon. There is a manual washing step as well as a drying step, but not a lot of detail is given about them.
Indeed you did.
IIRC the hydrochloric acid treatment was allegedly started back in 1921 which explains why the 1921 Morgans and Peace dollars and subsequent 90%...
At any rate, we don't know that the mint uses the same process of planchet/blank preparation for all of the various silver eagles.
That seems somewhat dated and not sure why it would be necessary here. As a practicing chemist, I used to make Copper(II)Hydroxide from Cupric...
That's a little different than the process described for the silver blanks at the SF mint. The implication is that a quenching bath is not used....
