Typically silver tarnish is silver sulfide, not what you stated which has me confused. Where did you learn about silicon being found in silver tarnish?

The dip can dissolve the silver sulfide from the surface, which will then be fresh silver and very susceptible to fast re-toning if not protected. As it stands, the native silver oxides and sulfide on the surface have passivated it, protecting the coin's surface to an extent. You take that away and more silver will react with the atmosphere. Repeating this process further removes silver from the coin's surface.

You can try MS-70 before going full dip if you want but your dealer can probably dip it for it if that doesn't work

E-Z-Est will greatly improve the eye appeal. Follow direction on the jar.

GrapeCollects- Whatever you decide to do, could you post pictures of the results? I think the mint luster is toast on this coin. MS70 plus dipping it, the coin will come out an ugly dull gray.

Sure, I think acetone first, then a dip and maybe MS70

If you're going to try all 3, MS 70 before dip. Dip is way stronger and if that didn't work MS 70 wont at all.
