All the dies come from the master die so they would all be almost identical. We all know no two items are exactly the same but what you are looking for Abdulah is not there. I think the coin (Error Hype) is getting desperate. The way that the coins are made now days make it very rare to get errors. That is why people get so excited over a new die clash which I think is cool but that's here nor there. I have a feeling people will be searching for ghosts in a lot of older coins and that will make identification even harder than it is now. I will always coin hunt. I have been doing it for a while and most of what you think you see you do not.... believe me...... Look again.. and look it up,,,, Most errors have been found already. If you find something new in a 60 year old coin it is probably PMD. ( Post Mint Damage ) Good Luck.
