[QUOTE="Oldhoopster, post: 5423754, member: 84179"]While I appreciate your enthusiasm, why do you believe it's a mint error and not PMD? Many of the responses you received are from members who are very knowledgeable of the minting process and have extensive experience collecting error coins. As they have said, there is no part of the minting process that would have produced a coin in that condition. However, copper is a very reactive metal and your coin has the characteristic appearance of environmental damage. While there is nothing wrong with disagreeing with the consensus of experienced collectors, you really need to provide some information on what could have caused the error at the mint. Just saying "It's a mint error" doesn't cut it, unless you provide some reasoning. If you believe it's struck on a gold planchet, can you provide supporting information? Do you have XRF data showing it's gold? (It's not too hard to find a shop who has a handheld XRF unit). Where/when/why did the mint make cent sized gold planchets in 1963? Many annual mint reports are available at the Newman Numismatic Portal if you want to do some research? You can also study the minting process on the following link.
