i was wondering from my understanding of how the minting process works it would seem to me that when a double die happens they will end up in the same rolls after minting and rolled. Ex. In 1955 when a double die was found were there 49 others in that roll? Of course I understand after put into circulation this does not apply. Or maybe I’m not correct on my understanding of the process from minting to the coins being put into rolls?
A simple way to explain it is that many coins are struck at once and they fall into a collection bin. At certain points the coins are inspected. If they find a problem such as a Doubled Die issue they will pull those coins out and destroy them. But it might be that not all the coins with the issue will found so a few end up in circulation for us to find. Then the coins are sent away out of the Mint to be rolled up.
After the coins are struck, they are fed into a collection bin, and the collection bins from several presses are loaded into ballistic bags that contain hundreds of thousands of coins from the several presses. This is how an error or variety gets mixed in with "normal" coins, and this happens before any coins are put into bags or rolls. Chris
You are correct Christopher, Very often our older coins were found grouped together in the same rolls. Due to changes at the mint, it appears that this MIGHT BE less common. However, while searching rolls of Sac Dollars several years ago that shipped directly from the mint, coins in the exact same die state were found together. How this still happens is a mystery to me.
The 1955 doubled die was not an error in production, just die die/hub production. 20,000 were minted before the doubling was noticed. Due to a cent shortage, and the cost in time and money in destroying them, a decision was made to just go ahead and ship them. Most were sent to Ohio.
It's a mystery to me, too, but I know it happens. I had three separate events happen to me. (You know about one.) When I searched a $50.00 (original) Mint bag of 1980 Lincoln Cents, I found 228 specimens of a "Clashed Y" between two of the columns of the Memorial, and all 228 specimens had the same markers on the reverse. On another occasion, I found a die break progression on the reverse of 27 specimens of 2001-P Kennedy halves that came from the same $100.00 Mixed P&D Mint bag. All of the specimens had the same marker on the top right of the shield. Chris
