A 2005 Roosevelt dime with great brilliance and detail ...... except it looks likes it is rusting from within. Yes it is a 2005.. I had to magnify it significantly to identify the "5" To me it looks like it is rusting. There are areas that appear to show the copperish core. See reverse just above the "N" in the word "ONE" (7 o'clock) Other areas that display green red or brownish appear to me to be affects of rust.. Could it be caused by poor plating of the outer layers of the coin? What do you think?? Gofy
Is there another explanation ? From reading the forum I understand that using PVC flips can leave a residue on coins that need to be carefully removed. Those entries did not mentin damage only a sticky residue. Also being a 2005 and found in circulation it is difficult to believe that this coin was in a flip at all or at least long enough to become contaminated. Are there other sources of PVC that this coin could have come in contact with? Gofy
It looks like some of the pocket change left on my dryer. Exposure to harsh chemicals like soap powder, bleach, humidity and heat can do this.
I do see what appears to be a couple small spots of corrosion but I do not believe that is what is causeing the color change. And I think we can discard the idea of PVC contamination having eaten through the clad layer. ("PVC residue" by itself is actually harmless. The damage is caused by outgassing from an old PVC holder absorbed by the residue and water vapor from the air that combine to form hydrochloric acid which the residue holds in contact with the coin. If that happens the surface can be etched fairly quickly, but it would probably take a hundred years or more to eat through the clad layer. Unless the acid is constantly replaced, the etching of the outer layer will consume the acid and the reaction will stop.) It looks to me simply like a discoloration of the metal. It doesn't appear to be a case of a partially missing outer clad layer. This is the best I can say from the images.
