Just how long can a silver coin stay fully original "white"?

Many of the silver dollars from the 1962-63 release were still fully original white even though they had been in storage since the late 19th century. What is the earliest silver coin you are aware of that is fully original "white"?
All glory is fleeting.

    I've had Mughal dynasty silver coins from the 1300's that were not toned nor cleaned. One on right is an example:

    If they're stored with little or no exposure to air or airborne contaminants, they should stay as minted indefinitely.

    He said that they were released in 62-63 not struck in 62-63. They were struck in the late 1800s.

    You mean 1500's since Mughal empire was not around 1300's . Nice mohur, btw. image



    What's the one on the right?

    I had coins that were stored in flips for 30+ years and they were untoned.

    True enough; on the other side, I've seen coins taken out of holders and left in a drawer start to tone within a couple of weeks.

    I think some of the mint bags of silver dollars showed a lot of variation depending on where they were within the bags....those close to the outside developed toning, those buried deep within stayed white.

    Tarnish is a reactive process, therefore the coin must be exposed to substances that will join with the silver...If none are present, then no tarnish. Cheers, RickO
