They are all different and of various strengths. But they are all also similar in that they all contain an acid, and it is the acid that does the work. And to make things even more complicated all of the coin dips can be used full strength or they can be diluted. And on what you dilute them with, and how much you dilute them, everything changes. </p><p><br /></p><p>That said, there is yet another variable that must be added into the equation, the coins themselves. And the coins can differ greatly ! And those difference greatly affect the outcome of the dipping process. For example, some coins can have a light but unattractive toning on them. Others may have a very heavy and thick toning on them, and others can be even worse, toned so badly that they are completely black. And even once you get to the black stage, there are yet different classifications of black. There is glossy black, semi-glossy black, and flat black. </p><p><br /></p><p>And last of all, there is the effect that the toning has already had on the coins before they coins ever get dipped to begin with.</p><p><br /></p><p>So the answers to your questions depend on all of the variables I have listed above.
