Cleaning coins

Our city has recently opened a "time capsule." It is a copper box
that was sealed into City Hall in 1938. The contents include several
coins, which are rather badly corroded. A local coin collector has
looked at the coins and valued them at varying amounts (most under
$20, but one worth several hundred dollars). He recommends cleaning
the coins with a silicone-based product called "Care." The mayor
wants to put up an exhibit and would like the coins to look
attractive. Any advice appreciated,
