recently I found a 2013 toonie in my change that has a core that is a real dark color, the outer ring is normal I wish I had better than my cell phone camera to take photos of coins. the best I can describe is a dark type of brown.
Also have a 2014 dime that I can see the copper around the reeding and looking like a rainbow affect around the c in Canada and some copper showing around the rim. Also a 2007 dime that is a off center strike on the date side of the dime it is shift over I say about a eight of a inch that is the best I can describe I can't take photos right now.
