Chaotech Valued Member United States 99 Posts	Posted 04/20/2008 02:27 am I am a pocket change surfer and today I pulled out a 2007 Monticello Nickel the front of it is normal nickel finish, the back is a nickel finish with a VERY bright bronze / copper color throughout most of the middle, as if the outter layer is very thin or weak... anyone know what causes this? does it increase value at all? I dont expect it to be a $100 coin but $5 is cool for a .05 nickel! Edited by Sap 04/22/2008 01:55 am Report this Post to the Staff

Chaotech Valued Member United States 99 Posts	Posted 04/21/2008 06:54 am i will look into sintered planchets... I've never seen one before so I dont know what they look like but it would be cool to compare the two. Report this Post to the Staff

More than likely, it was set on something and toned. Report this Post to the Staff
