Sorry right now most people would get mean and maybe anoid. I'm not going to do that though you seem like a nice guy and I myself is also a nice guy so I want to help you out. Its just that I know for shore I told you to read floaters posts 2 times and I think Floater even gave you a link just click and read pretty simple, but there are a lot of post there from a lot of people that you have to sort threw so I'm going to spell some thing out here as clear as I can.
1: use distilled water (if you use any other water it is conductive because all of the iron and minerals in it they will deposit on the coin and make it all kinds of dirty and even electro plate it this stuff that makes it conductive is called microsiemens)
2:electrolytee you can use. ( you need an electrolyt because believe it or not water is
not conductive its the minerals and metallic crap found in water that is but there is none of that crap in distilled water so you need an electrolyte to make it conductive without introducing metals and minerals that will give you problems)
-salt (not iodised it could give you a problem)
-baking soda (sodium bicarbonate) I'd say this may be best over the salt if your just trying to use stuff around your house
-Soda Ash (sodium carbonate) This is what I use and is what floater moved on to using as far as I know. You can get this fairly cheep at a pool supply store I use "Aqua Clear brand (but brand dose not matter) pH increaser" and the ingredients is what is important look at the ingredient's you want it to see
"ingredients: Sodium Carbonate......................100%"
-There are other things to use but this should be enough info for you.
3:a non conductive container like plastic or glass (plastic folgers can right Floater
someone posted to you about they tried it with a metal can and they or there buddy touched it and got shocked)
4:anode and cathode I'd say the cheepest and easiest is Stainless Steel other metals can give off stuff that can deposit on the coin or eat it away. There is other stuff like the conservitor uses platinum wire (not cheep or easy to find)
I make cool things out of stainless at work cause I'm a machinist but for you the easiest thing is to get some silverware that is made of stainless steel try the dollar store, good will, or some type of thrift shop to make it really cheep

ower unit the rectifier is awesome and I'll be getting one in a few weeks when I might have the money (thanks Floater) But this here in the picture below is a great cheep reliable unit you can pick up at radio shack
here are the specifics on this unit in the picture below:
-the name of it is, Lead-Acid Lantern Battery Charger (radio shack brand) it plugs into a standard 120vac house outlet
The output is 6 volt DC and 500mA
cost here in PA is $6.99 thats what i payed for the last one here in the picture
and the ends are the alligator clips that is how it comes I did not modify in any way at all.
500mA is on the high side for electrosys but factor in the variables like the electrolyte consentration and type, the size of the object, and the distance of the cathode and anode I always check mine with a digital multi meter (radio shack also) and in the solution I can get anywhere from 200mA up to 350mA that shown on the multi meter is what the coin is actually cooking at I just play around and get it were I like.
This unit works very well and is very cheep so you may want to buy a few and cook a few coins at one time all in separate tanks and if you get cheep SS silverware you could get extras also. do not do more that one coin at a time if you do not know what metal it is the more noble metal will eat away the less noble metal this will leave you with an eaten away coin and another that is plated with the metal of the now junk coin so that plating will make that one pretty much junk also. this setup i give you here should be cheep enough to have a few electrolysis set ups going at one time to clean single coins each and get done faster. Your coins are encrusted so knowing the metal comp is not really happining some one at a time is your rule to fallow (or one per setup
right?)
Good luck and let us know how you do and will help with all of the ?'s but I'm telling you to read Floater's posts please read them before you ask anymore ?'s. If you have a problem not understanding something when you read it just ask no problem just ask. but please read them.
hope this is clear enough to help you.

It was my first photo shop experiment. I had the old stereo headphones and then enlarged them in Photo shop and then put it on my mug. Great stuff. Later. HH
