That's a very sweet die crack. There's just something about them die cracks that does it for me. I enjoy them. Plan on owning more in the future.
BTW that's on a proof..

What had me stumped most of all was why most of them was cracked up by the top of his head. Must be in the design. Made a weak spot in that area. RWBs book had all kinds of cool information on how dies were made, annealed, and cooled in various ways to help keep them from cracking. There's something about that spot on his head that's hard on the dies.
It could be the point where the pressure is highest..

You know copper degrades too, which is why red coins turn redbrown and eventually brown. They can also corrode pretty nastily too...
Yeah but not as easy as the zinc..

Never really know when the die will break. It could be after the first coin struck. It could be because of improper annealing..

The proof cent blanks are prepared with a double thickness of copper plating, and all 2009 cents in both uncirculated and proof sets were the classic bronze alloy. It’s why a full set of 2009 cents consists of 20 coins. Four designs times 5 “types” - zinc P, zinc D, bronze P (only in uncirculated set), bronze D (also only in uncirculated set), and bronze proof S.
Still to thin. Can still see inconsistencies in the field. Needs to be a solid copper cent like in the past..
-
Problem is even on ms70 and pf70 coins you can tell the zinc is under the copper layer. Irregularities where the copper and zinc meet show through even on high grade coins.. So I feel if it were a solid copper cent you'd be getting a much better struck coin that would last much longer..
-
Should be old time solid copper for reasons mentioned in previous post.. This is better for collectors not worrying if zinc coins will degrade in the holder.
-
you buy a slabbed Pf70 or MS70 modern cent for big dollars and then 20 years later the zinc below the thin copper plating starts corroding and starts to blister the plating?? Does the value or grade of the coin go down or would it stay the same? Seems like it could be risky for plated coins...

I would suggest calling NGC and asking them.

Would have to get a 68 or higher to be worth TPG grading.
At great risk I removed from cellophane with gloves and handled coin by reeding only to snap these two two fine images.. Any chance for a high grade?? Looks so much better then the other coins in the uncirculated set. I don't see any nicks, dings or scratches on either side of the coin..

A good start would be a search of proof die crack which has been printed on many of my holders.. Different dates and denominations could also narrow it down. NGC should offer this service..

Only if the data exists and you have access.
Well the data would exist on the slab information sticker so a computer should be able to spit out a total number for a given coin..
