Some very nice nickel errors posted! Here's another one, which is a scarce combo error. It is a Jefferson nickel double-struck on a 10c planchet.
Here's the write up on it:
NGC 1984-P Jefferson nickel double-struck 70% off-center on dime planchet. The coin is struck on the much smaller clad planchet of a dime, and weighs 2.3 grams, and as a result, some of the outer design details are missing on the coin.
Nickels struck on dime planchets are generally a scarce error type, but are available. However, off-metal double-strikes on dime planchets are rare, and few are known this this. It is particularly desirable since the 2nd strike shows design on both sides, and also because the coin's date and mintmark areas are visible. Additionally, it is problem-free and attractive.
The error occurred when a dime planchet was fed into a press that was striking nickels, and was struck twice, with the 2nd strike 70% off-center.
My all-time favorite Jefferson Nickel mint error was the unique 2 Headed. Every other modern U.S. coin struck by 2 obverse dies or 2 reverse dies are reverses!!

Here's another neat one--you don't see these very often.
The write up is below:
PCGS 19xx Jefferson nickel indented by a Roosevelt dime planchet. The indent is close to a dime size, with a slightly larger size because, when it was struck, it expanded slightly in size.
The error occurred when a dime planchet was fed into the nickel press while resting atop of a nickel planchet, and was struck into it. It then fell away, leaving a "dime shaped indent" in the nickel's obverse.
A nice example of the error type, with about 80% of the dime's shape within the design of the nickel. This makes it more obvious and more eye-catching.
This is a very scarce error type, and only a small number are known. An approximate estimate would be that 10-15 nickels indented by dimes are known.
