VAM-4 Die Fracture Mechanics
Under the high hydraulic forces required to strike 90% silver Morgan dollar blanks (upwards of 140 tons pressure), working reverse die #4 developed a major stress crack extending from the incuse eagle's beak into the field:
Because metal fills into the fracture on the die face, the resulting coin exhibits a raised line of positive silver that appears to project like saliva spitting from the eagle's beak.
1891-CC Carson City Mintage & Survival
The Carson City Mint struck 1,618,000 Morgan dollars in 1891. VAM-4 is one of the Top 100 VAM varieties and commands a significant premium over standard 1891-CC dollars:
Collectors in the Carson City Registry and the Society of Silver Dollar Collectors specifically compete for high-grade specimens of the 'Spitting Eagle'.

Frequently Asked Questions
What is the 1891-CC 'Spitting Eagle' Morgan Dollar?
It is a famous Carson City die variety (cataloged as VAM-4) characterized by a prominent raised die break extending downwards from the eagle's beak, making it look as though the eagle is spitting.
What does VAM mean in coin collecting?
VAM stands for Van Allen-Mallis, referring to Leroy Van Allen and A. George Mallis who cataloged all known die varieties of Morgan and Peace silver dollars.
Is the 'Spitting Eagle' line raised or sunken?
The line is raised on the surface of authentic coins. Because it was caused by a sunken crack in the steel die face, the striking pressure forced planchet silver up into the fissure.
How rare is the 1891-CC VAM-4?
While the 1891-CC has a mintage of 1.6 million, VAM-4 was only produced by one specific reverse die. In Mint State grades (MS-63 and higher), it is quite scarce and commands strong collector premiums.
Can the die crack wear away on circulated coins?
Yes, on heavily worn coins (Good to Very Good), the die crack can become faint. However, on Fine to Extra Fine coins, the break is typically still distinct and certifiable.
Are there counterfeit 'Spitting Eagle' coins?
Yes. Counterfeiters sometimes scratch or solder lines on common 1891 Philadelphia dollars or apply fake 'CC' mintmarks. Authentic coins have raised die lines and genuine Carson City mintmark positions.
Does PCGS or NGC put 'Spitting Eagle' on the certification label?
Yes! Both PCGS and NGC recognize VAM-4 under their variety attribution programs and will print 'Spitting Eagle' directly on the certified holder label.
