Silver (and to a lesser extent copper) tones when exposed to certain chemicals. When coins are left sitting in rolls or bags for many years, the chemicals cause the coin to tone, or change colour. Occasionally what happens is that it creates multiple colours that looks like a rainbow. Attractive toning is desirable to many collectors. However, one needs to be aware that toning can be faked fairly easily, so I personally would never pay extra for a rainbow toned coin unless it was sold in a reputable coin shop and graded by a reputable third party which detects artificial toning and will either note that it is artificially toned or refuse to slab the coin.
