Jbuck - Thanks! Vermontensium - I am not using Nic-a-date, however, what I am using is pretty comparable, just a lot more potent. You probably need a larger volume of Nic-a-date than you currently have. There's a lot of metallurgical things going on when you dip the whole coin - I can't speak from the position of absolute, knowlegable certainty about ions being cast off and electrolysis and half a dozen other things that may or may not actually happen when you dip the nickel, but I can tell you I get better results when I place it into a larger volume as opposed to a lesser volume. If you don't have a large volume available, I suggest you "paint" it onto one side, let it work, rinse, and then do the same on the other side. I used to do it that way with GREAT results, but it became tedious. Even with the large volumes I use, I still get SOME that come out looking like trainwrecks. A lot depends on the coin. Poorly prepared planchets can result in poor restorations - 90 years later! (It will also help if you clean the coin prior to it's "bath"!) Finally, I restore the date first. If the date doesn't come back strong, the rest of the coin will probably be just as weak. If it's weak or weird in any way, pitch it and try another. (It will NOT hurt to fully restore a nickel that has had it's date revealed FIRST!)
Oh...and MRH757, the answer is "maybe". It certainly won't hurt it's appearance, although it's unlikely to totally correct it.
