<p>[QUOTE="GDJMSP, post: 1790786, member: 112"]There is no sometimes about it, all coins tone, period. At the very moment that a coin leaves the dies it begins to tone. But there are many, many degrees of toning. And at first it is a very slight change where the freshly minted silver color turns just a tiny bit darker. And it progresses from there.</p><p> </p><p><br /></p><p> </p><p>Actually every worn silver coin you have ever seen was toned. Yes, the toning may have been removed if the coin was cleaned or even harshly cleaned, but before the cleaning was done the coin <u>was</u> toned. It is impossible for it to be otherwise.</p><p> </p><p>However, I think when you say "I rarely see worn silver tone " what you really mean to say is "colorfully tone ". For example, here are some pics of worn silver dimes.</p><p> </p><p><a href="http://www.google.com/imgres?hl=en&biw=1163&bih=620&tbm=isch&tbnid=TqluGmO0o5ThkM:&imgrefurl=http://coins.about.com/od/coingrading/tp/How-To-Grade-Mercury-Dimes.htm&docid=atm2q8e3SxxR2M&imgurl=http://0.tqn.com/d/coins/1/0/9/J/-/-/US0010-Mercury-Dime-XF40-PCGS.jpg&w=1024&h=521&ei=AeM-UvPaB4n-9QScyYHICg&zoom=1&ved=1t:3588,r:0,s:0,i:81&iact=rc&page=1&tbnh=160&tbnw=315&start=0&ndsp=17&tx=234&ty=104" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.google.com/imgres?hl=en&biw=1163&bih=620&tbm=isch&tbnid=TqluGmO0o5ThkM:&imgrefurl=http://coins.about.com/od/coingrading/tp/How-To-Grade-Mercury-Dimes.htm&docid=atm2q8e3SxxR2M&imgurl=http://0.tqn.com/d/coins/1/0/9/J/-/-/US0010-Mercury-Dime-XF40-PCGS.jpg&w=1024&h=521&ei=AeM-UvPaB4n-9QScyYHICg&zoom=1&ved=1t:3588,r:0,s:0,i:81&iact=rc&page=1&tbnh=160&tbnw=315&start=0&ndsp=17&tx=234&ty=104" rel="nofollow">http://www.google.com/imgres?hl=en&biw=1163&bih=620&tbm=isch&tbnid=TqluGmO0o5ThkM:&imgrefurl=http://coins.about.com/od/coingrading/tp/How-To-Grade-Mercury-Dimes.htm&docid=atm2q8e3SxxR2M&imgurl=http://0.tqn.com/d/coins/1/0/9/J/-/-/US0010-Mercury-Dime-XF40-PCGS.jpg&w=1024&h=521&ei=AeM-UvPaB4n-9QScyYHICg&zoom=1&ved=1t:3588,r:0,s:0,i:81&iact=rc&page=1&tbnh=160&tbnw=315&start=0&ndsp=17&tx=234&ty=104</a></p><p> </p><p><a href="http://www.google.com/imgres?hl=en&biw=1163&bih=620&tbm=isch&tbnid=oRFY6knBpqwXlM:&imgrefurl=http://www.thehappycoin.com/1942_41_10c_Mercury_Dime_NGC_CAC_XF_40_p/soldc973.htm&docid=99l1br8w_SXBoM&imgurl=http://a248.e.akamai.net/origin-cdn.volusion.com/pwhvg.djrxu/v/vspfiles/photos/SoldC973-2.jpg&w=501&h=499&ei=AeM-UvPaB4n-9QScyYHICg&zoom=1&ved=1t:3588,r:9,s:0,i:108&iact=rc&page=1&tbnh=181&tbnw=175&start=0&ndsp=17&tx=107&ty=96" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.google.com/imgres?hl=en&biw=1163&bih=620&tbm=isch&tbnid=oRFY6knBpqwXlM:&imgrefurl=http://www.thehappycoin.com/1942_41_10c_Mercury_Dime_NGC_CAC_XF_40_p/soldc973.htm&docid=99l1br8w_SXBoM&imgurl=http://a248.e.akamai.net/origin-cdn.volusion.com/pwhvg.djrxu/v/vspfiles/photos/SoldC973-2.jpg&w=501&h=499&ei=AeM-UvPaB4n-9QScyYHICg&zoom=1&ved=1t:3588,r:9,s:0,i:108&iact=rc&page=1&tbnh=181&tbnw=175&start=0&ndsp=17&tx=107&ty=96" rel="nofollow">http://www.google.com/imgres?hl=en&biw=1163&bih=620&tbm=isch&tbnid=oRFY6knBpqwXlM:&imgrefurl=http://www.thehappycoin.com/1942_41_10c_Mercury_Dime_NGC_CAC_XF_40_p/soldc973.htm&docid=99l1br8w_SXBoM&imgurl=http://a248.e.akamai.net/origin-cdn.volusion.com/pwhvg.djrxu/v/vspfiles/photos/SoldC973-2.jpg&w=501&h=499&ei=AeM-UvPaB4n-9QScyYHICg&zoom=1&ved=1t:3588,r:9,s:0,i:108&iact=rc&page=1&tbnh=181&tbnw=175&start=0&ndsp=17&tx=107&ty=96</a></p><p> </p><p>Both of those coins are toned to different degrees.
