Captain Jack Valued Member United States 171 Posts	Posted 07/11/2015 07:57 am I've been thinking for a bit if a Morgan or any other coin were put into a drawer of an old oak built cabinet or etc. and left for a while and if that might tone it some. I've only been thinking like this because to me, it seems like some of these coins that are toned may have come out of drawers originally and that's how they may have been toned through the last 100 years?

ChildOfTheWheat Pillar of the Community United States 5828 Posts	Posted 07/11/2015 09:37 am Toning is a natural reaction that occurs when silver reacts with the air. It can be caused by other things, but this is the most common way. Report this Post to the Staff
Cascade Pillar of the Community United States 7390 Posts	Posted 07/11/2015 10:41 am Here is some collegiate level reading on toning and how it naturally happens and how to distinguish between natural & artificial. This site should become your "bible" if you're interested in toned morgans... http://www.jhonecash.com/coins/tonedmorgans.asp Report this Post to the Staff

This is how many morgans naturally toned from being in canvas bags sitting in treasury vaults for over half a century. READ THIS too if you haven't already http://www.pcgs.com/books/silver-do...r14-001.aspx Report this Post to the Staff

llewellin Pillar of the Community United States 1005 Posts	Posted 07/11/2015 10:49 am The short answer is the silver reacts with sulfur compounds in the air to create a thin film of silver sulfide on the coin. Interference between light reflected from the film-air interface and the silver-film interface selects for certain colors reaching your eye that depend on the thickness of that film. Depending on how much sulfur is outgassing from the oak and the temperature/maybe humidity as well, the film might grow thicker than expected in a short period of time, creating a black toning.

This is THE sight all lovers of toned morgans should eat, sleep & breathe until it is memorized. Then read it another 10 times for good measure Report this Post to the Staff
