on crusty silver coins ?

I use an aluminum can instead.
 
I have, and hadn't much success with it. For my last trick, I got fed up with the process, and decided to vigorously rub a hot paste of baking soda and lemon juice between my finger and thumb. Now I have a shiney crap coin.
 
I tried the process the "land" guys use on their tarnished coin with the foil process - did not touch the crust on half i just found
will have to use electrolysis eventually
 
Works best on tarnish. Heavy sulphide jackets require other methods. After the sulphide crust is removed then try the foil method.
 
I have had good success with using the foil method on solid black colored silver coins. It seems like baking powder with the right about of salt using the dull side of the foil works best. You know it is working good when the coin is bubbling and smell of rotten eggs. When its right the foil will be blacked. I normally keep the water boiling on the stove to repeat the process quickly. Between it process I rub it with baking powder loosing what I can before adding a new batch of salt, and powder.

I used both baking soda and baking powder. Not sure which one works best, seems to work with both. But sometimes it does seem to work better. You can smell and see it working. I think the success is a combination of things. Even adjusting the foil to have the most contact with coin.
 
I use to do the route of electrolysis.. and baking soda .. now I find so much silver I like the fast method .. crunch off the cookie and hit it with a nice wire brush on the drill.
 
IVE BEEN MEANING TO ASK YOU THAT - ALOT OF YOURS COME OUT SO THIN AND YOU CLEAN SO QUICK AFTER HUNT - I HAD A FEELING YOU WERE HITTING THEM WITH A DREMEL TOOL OR SOMETHING -
SOME CRACK WITH EASE - SOME DONT - ONE I JUST FOUND MIGHT BE A SEATED OR PROB A BARBER - EVEN THOUGH NOT GONNA BE WORTH ANYMORE EITHER WAY - DID NOT WANT TO END UP WITH A SILVER RAZOR - WILL WAIT AND DO ELECTRO ON IT EVENTUALLY

Here is something I tried on the very few crusty silver coins we find down here in Florida. I was making coin rings and was annealing some silver coins and thought I'd try heating the "black cookie coin" with the propane torch. After heating it I dropped it into some water and the cookie came right off. Only tried it once or twice and seemed to work pretty good. Might be worth a try.....like I said I don't find enough down here on these re-nourished beaches to refine the process .

I had some success freezing them in water first to knock the cookie off.

Really the wire brush removes almost nothing.......... but the tarnish or black ............but it does leave a few marks. The silver that is thin like a razor comes out of the water like that, most of the time you can tell once you have taken the cookie off...here are a couple of thin dimes..with the cookie removed and not really worth cleaning.
