Hello all!
So this beauty error coin came recently as a part of an on-going lot I'm aquiring. I purchased a few of these britannia cents, and noticed this one has a serious planchet problem. The metal seems to be blistering from the inside out, on both sides. The coin is in decent condition, and does not appear to have been whizzed or cleaned at all. Any comments or ideas as to what may have caused the error, and to finally approve/disapprove it. Thanks for all the input!!
