Die Rust?

speety

On jade rare coins they have an 1804 MS-63 BN large cent which was struck with cracked dies and has lumps all over the coin. Is this from rusty dies? I've never really understood what result rusty dies have on a coin and this coin looks like it was struck very soon before the die broke up. Can any of the copper experts tell me the variety and how much further this die cracks before it's taken out of use? Just thought the coin looked interesting.

Yes. It is a restrike of the 1804 Cent. They used from original dies which were heavily rusted and cracked. From the 2003 Redbook

"A fake 1804 was manufactured from discarded dies. An altered 1803 die was used for the obverse and a die from the 1820 cent was used for the reverse. They were struck c[irca] 1860 to satisfy the demand for this rare date. Known as the 'restrike', it was a patchwork job and is easily distinguished from a genuine 1804 cent."

Thanks for the info, it's a neat looking coin even though it is a restrike, i like it.

Iron and steel will spall when they rust. This means the oxide does not remain attached to the corroding object but instead lifts away and flakes off leaving the metal exposed to further corrosion (This is in comparison to silver sulfide or aluminum oxide which cling to the surfac and provide a potective barrier to further corrosion). This results in pits and depressions forming in the iron or steel surface is th corrosion continues. If the corroded die is then used again the planchet metal will fill those pits during the strike and result in raised lumps on the finished coin. As can clearly be seen n the picture posted by Moose.
