Here are my two favorite toned dimes. One is silver and had this beautiful purple tinge to the edges. One is clad and has turned almost completely gold. Both have been stored in Littleton folders, although other coins in the same folder have not toned like this. Just wanted to share!
Wow, the 2007 toned really quickly for a clad coin. It's interesting how the process starts, I hope they both keep going Very Nice.
