I belong to another forum dedicated to
Half Cents and I had a conversation earlier today about this coin with one of the knowledgeable moderators on the subject. I wanted to know why there wouldn't be a doubling on my coin on "LIBERTY" or on the reverse. Here's how the conversation went.
Me: Do you think this is a real double struck? and if so can you explain how the strike process works as to why there is no doubling on the reverse or on the word LIBERTY but only just on the obverse face?
Him: Yes, it is a real double strike. The shallower portion of the obverse often will get "erased" when the 2nd strike occurs. That's why only the face is doubled. This is not unusual at all, I have many examples just like this one. The reverse gets struck into a blank planchet flattening the reverse somewhat. This is what we call a brockage maker, because the blank that it struck becomes a brockage. Hopefully this all makes sense. If you own this, you should share it with the
Half Cents Facebook group. Mint errors are so much fun. I love them.
Me: So the reverse is struck at a different time than the obverse then?
Him: No. A blank planchet got fed into the press at the same time. So the first strike happened, then that coin failed to eject and got caught in the press, a 2nd planchet was inserted and that's when the 2nd strike happened. This is why only the obverse shows doubling. The reverse was sitting on top of a blank planchet'. It hit the blank planchet squashing the reverse details somewhat.
Me: so there's another planchet with just a reverse on it.
Him: Yes! It would have created a reverse full brockage.
Me: that makes sense ...I can explain it now to someone else lol.
Him: Yeah, they are a bit of a puzzle sometimes. you just have to work it out in your mind. It's really just simple physics in the end. Here's one that I have that is the twin to yours.
