Your post was well assembled, the photos were self explaining, and the information provided was probably something that even the most "jack of all
trades" individual never learned. I even salved it for adding to my personal how-to collection. I look forward to your Gold refining walk-through.
Let me give one advantage to your method - portability. Instead of having a large, loud, bag of coins one can shrink it down to a few pebbles while
maintaining a near identical amount of silver.
But there are three disadvantages I can immediately think of, especially for those who plan to use this silver for barter.
1) Silver, like any precious metal needs to be recognized as NOT FAKE. These drops could be any numerous metals, and most people do not carry the
tools to process and test if the metals are pure. Not suggesting the method does not produce 99.9% pure silver, I'm just saying a layman on the
street might not want to "take your word for it".
I DO NOT recommend melting down recognizable coins for their silver content. You destroy any credible proof of minting. Most people who would be
interested in accepting silver know how to look up the metal content based on the type of coin.
2) You lose wealth in the process. It may not seem substantial but if you do this more than a few coins and you will have lost all your copper value
(which does add to the melt value) and you will have lost a finite amount of silver due to the process of dissolving it, precipitation, filtering it,
and rinsing it.
3) the tools to refine the silver may out cost the metal value its self. Depending on your abilities to obtain all the tools needed it may cost more
to process the metal than it was to acquire it in the first place. Yes most are common, but after you use them for the refining process you may never
want to use them for anything else again.

Just a few things to keep in mind. I'm sure most of you that are collecting silver are doing so as a hedge against inflation as it's a poor man's
gold. But some plan to barter with it when SHTF. So unless you plan to make jewelry (you can buy jewelers silver for little to no premium) or
Colloidal Silver . I do not recommend performing this process for any more than to learn a
new chemistry trick.
Most people will accept Silver or other precious metals as payment for spot value or below. Most people will only sell a metal at above spot value
(the difference being called "premium"). So remember the cost of refining adds to the cost of purchasing the metal, meaning you may be paying more
for a bartered item after processing than you would have prior to processing. (unless there is a premium market for refined silver, like industrial
purposes, and then you might luck out and trade it for a premium.)
