You're probably looking for an equivalent of something called Nic-A-Date, which is an acid that can bring out the date on a worn buffalo nickel. Unfortunately there isn't any commercial product like that for copper coins.
Nic-A-Date works because most dateless buffalo nickels are the result of a design defect that left the date higher than the rest of the coin when new, so it wore off first. When a coin is struck the impression slightly deforms and compresses the metal below its surface, and Nic-A-Date etches away some of the uncompressed metal revealing the "ghost" image of the date below the surface.
The problem with any acid treatment is that it damages the coin's surface. Even if you were to reveal a valuable date, the coin's collector value would be significantly reduced or even eliminated.
