Well I'm sure I'm going to ruin whatever I use for the experiment, that's why I'll pick up some "samples" just for that purpose. I'm not about to try it on any of my collection. Maybe a few of several different patterns" But I agree that the larger coins might be better (Morgans, Commems, etc..) And the SAEs will be interesting if for the composition alone.

50% distilled water to dilute the Jeweluster. Don't be stingy either. Use the Jeweluster for a few coins then THROW IT OUT. Don't use 'old' Jeweluster (remember there are contaminates left in it from the coins you've dipped) and NEVER dip copper* or clad or nickel in the same mixture of Jeweluster/water with silver.
*You should never dip copper, period- but if you do-
But braddick, In the name of Science, you know I won't be able to resist chunking at least one copper in there?
I'm envisioning a series of useful careful experiments, where we all can contribute and study the results. Once that begins to wind down, I get to the part I'm really interested in:
How long can a coin (each variety?) sit in this stuff before it completely dissolves?!? Evil I know, but I have to know the answer!!!!
And with a webcam monitoring the extermi...I mean experiment...it could be "fun for all!"

It's good to see you guys experminting because then you will know first hand what to look for in doctored coins and be better collectors because of it. BUT, if I start seeing your expermints selling on sleazeBay I'm going to be very very angry.
Change that we can believe in is that change which is 90% silver.
According to Bob Campbell, immediate past president of the ANA, "you can dip a coin up to seven times and there is not a grader out there that can tell it's been dipped". In the same speech he also said "if a coin dealer tells you he doesn't dip coins, he's lying". (FUN Show, 2001, Orlando)
<< <i>Just by looking at a coin, or picture of a coin, is it possible to tell if it has been dipped? >>
..........no not always........however next time you go to a show, notice how many silver coin look dead looking, lack any luster or shine, they just seems to lay there lifeless looking........an off gray color......thats a good way to tell.........
If you see a brownish toning around the periphery of a dipped coin, it's because it wasn't rinsed properly afterward.
After dipping and rinsing with water, rinse in a baking soda and water solution to neutralize any acidic residue that remains on the coin. After the baking soda rinse, back to a water rinse and then finally dip the coin in acetone to remove any water from the coin that would cause spotting. I've tried this on a Morgan dollar that had splotchy gold/light brown toning and had good results, so it should work good for your experiment. Oh, by the way, I used jewelustre with a 50/50 dip to water mixture.

You can expect a different result between a Morgan and a Silver Eagle.
"Get some cheap coins off ebay that have already been "swimming" in foreign substances to practice on, maybe he will give you a deal."
May not be a good idea either, as you don't know what they have already been subjected to.
What I used for my first experiement: I used the coins of an already unattractive and inexpensive proof and mint set (better control speciment - nothing SHOULD have been done to them yet.)
Oh, and you just have to dip a Sacagawea for $hits and giggles.
Maybe I'll look for some cheap or spotted Mint Sets...Sorry Lucy, but it looks like Franklins are back on the list
And Gilbert...thanks for the Sac idea! I hadn't even thought about that yet!

The Eagle will look really goofy?
We'll use our hands and hearts and if we must we'll use our heads.
