The Carson City Morgan that Isn’t


The Carson City mint closed in 1893, but 7 years later, the mintmark appeared on a Morgan dollar in New Orleans, making this variety one of the most popular in the series.

So how did the 1900-O/CC Morgan Dollar happen?

When the Carson City mint closed, its dies and other minting equipment were sent to Philadelphia Mint. To save funds, rather than make and ship new dies to New Orleans, a Mint employee was tasked with polishing the die, removing the CC and adding the O. As it turns out, he wasn’t a very good employee, failing to remove the CC before striking the “O” over it, resulting in the “O/CC” variety.


Hobbyists who collect all CC Morgans typically add the 1900-O/CC to their collection. It also is required for some set registries. And VAM enthusiasts (VAM catalogues Morgan varieties) especially like the overmintmark error, designating it with these distinctions: VAM-7, VAM-8, VAM-10, VAM-11, VAM-12 and more.

We’ll use VAM designations to show the difference in prominence of the overmintmark.


Hobbyists favor VAMs 10-12 because of the prominence of the overmintmark. All of these above varieties are on the Top 100 most desirable Morgan VAMs.

All 1900-O/CC varieties are valuable, typically more than $100 in any worn condition. At VF40, value rises to $300; AU55, $450; and MS63, $1400.
