1980 P Quarter - Lump

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I found a 1980 P Quarter today, not great condition due to the dirt and such.  But it was in a stack I had been keeping for a 'piggy bank' type deal, and I noticed there was a small gap in the stack.  So, I pulled it out and there's a bump about the size of a bb UNDER the 'head' side.  The bump is right under the 'We' and part of Washington's neck.  The letter is still very legible and appears to be underneath.  Also, there isn't a dent in the back, so I know its not like someone tried to shoot it.  I've seen other being called 'cud' but the error on those were on top of the coin, this seems to either be an error of the copper inside or the inside of the head clad.  I couldn't find anything on rarity of this kind of error.  Any information is appreciated.  Also, should I try to clean it with baking soda/water?  If the picture quality is too bad, I'll post new ones later.

	Hello. Your coin was exposed to extreme heat outside of the mint. Trapped gas between the clad layer and copper core expanded from the heat to form the bubble. Additionally, your coin has become discolored from being exposed to the heat. This "bubble" effect shows up quite frequently and is often misdiagnosed as a mint error.
