It sounds like you're looking for the equivalent of Nic-A-Date, an acid that's used to bring up the dates on worn buffalo nickels. However, silver is a much softer metal than nickel and to the best of my knowledge there is no similar product that can be used on silver coins because it would melt too much of the surrounding metal.
In any case coins that have been treated with Nic-A-Date are considered to be damaged so they don't gain any collector value. Dateless coins are effectively "culls" that are worth either their face value or their precious metal content, whichever is higher, but they have no extra value to collectors.

What acid will restore dates on copper coins?

Make a solution with the acid and water, soak the coin for a short time, then gently scrub with a soft brush to reveal the date. Be cautious when using acids to avoid damaging the coin.
What chemical will restore dates to copper coins and pennies?
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.
How do you know if a coin contains silver?

If they are collector coins, it is better to sell to a reputable dealer. If they are junk silver coins craigslist and eBay are your friends, but dealers and jewelery stores will usually buy them too.
