I know die cracks are common but...

I know die cracks are common but, how common is it to find a series of them from the same roll? I've been going through some Presidency mint rolls and came across 9 very similar cracks in one roll of Phillie's.

It’s not all that uncommon. I found 23 Lowell quarters with the same die gouge in the same roll a week ago.

 

Thanks

 

If they were struck with the same worn die and all landed in the same mint bag that went to the destination they were going to be rolled then there is a good chance for them to be found together! Simple explanation.

 

Yes, it is fairly common. I had a roll of Alabama quarters where half the roll all had the same cud (7 o'clock):

 

Just two weeks ago I found 8 of the same DDR in a couple of old rolls of 1960 LMC's. That was a good day, and the title of my post.

True, short ones have little premium. Long ones can have a nice premium and are not as common as the short ones as in your post. Coins with many die cracks have even more value. Such as:



As you can see, this die was on its last legs!! I probably missed one or two,
Gary in Washington

 

I'm going through a solid date box of 2019P cents, have 12 rolls to go and so far 13 rolls of die cracks obverse and reverse. Actually they are better than most found this way. Nearly all have a crack in the hair, one at each end of the banner and a crack at the top left of the shield. All on the each coin.

 

I found 39 nickels with the same die cracks in a mint roll of 40. Fun to find.

 

It's fairly common but you should be able to see a progression as the crack grows.

 

It is *extremely* unlikely that you'll be able to tell any progression from 10 consecutive coins. That die will strike 1,000,000 or more in its life. Unless there is a significant catastrophic event, 10 coins is nothing in the life of this die!

If you were fortunate enough to get individual coins thousands of strikes apart, you could probable trace the growth of the crack. Early US coin collectors do exactly this sort of die study - they'll bring dozens and dozens of examples of known die varieties to a meeting and compare little differences in die cracks, figuring out exactly how it progressed.

For something like a dozen found in a roll, however, I'd expect every single one to appear exactly the same unless you're using an electron microscope!

 

It just depends on the Mint's production and how it was bagged, then rolled. I've seen it happen.

 

It's more rare to find a normal coin. lol

 

I've questioned why conditions like that wouldn't create some sort of variety. I'm guessing it's because it is not consistent enough.

 

Yes. Understanding manufacturing processes is very important. There are so many process variables. I think every coin that comes out in the business strike category is different from the next in one minute way or another. But, it makes it interesting enough that collectors can have fun with it.
