I wanted to share my newest and very exciting pick up! My first (and probably only ever) two-headed coin. I believe this to be a first-strike brockage, which is why the mirror image is so pronounced.
There was a member a few years ago who didn't care much for mint errors. He was a British fellow. He stated silly things such as "British people don't make such a big deal on mint errors" " The Royal Mint's quality control is better than any US Mint and they don't have mint errors or as much errors escaping their facility" I don't know what his point ever was but his statements were always wrong in my opinion.
Most British coins are struck with the reverse die functioning as the hammer die. If that was the case here, then this brockage appears on the coin's upper face. Is there any sign of a partial collar lip, as that would tell us how the dies were set up.
I do remember that conversation! He seemed quite put off that there could even be British errors and suggested a proper Brit would return them to the mint. It’s going to be a while before this is in my hand, but I will try to get photos of the edge as best as possible and get back to you. Always an honor when you take interest in my coins
Nice there. Haven't seen too many modern brockages. mike diamond please check on definition of blockages as a retained coin between the dies then served as the "die" for the next coin. I will post a true "double tailed" penny from 1964 shortly which was struck from two reverse dies.
