ex-Omaha Bank Hoard.
The 1941-S Jefferson Nickel is considered to be one of the more common dates as it has a relatively large mintage of over 43 million coins struck. In circulated grades and up to MS66 condition without displaying the Full Steps details on the reverse it is fairly common and obtainable without paying any significant premium. In MS66 with the Full Steps designation it does become a bit more difficult to find and many examples in this condition or higher have probably already been certified. In MS67 condition it is very difficult to find and less than a dozen examples are known to exist with none being finer.
