The term odd is used in our hobby on items that are found un naturally on the coins surface,and devices. Here's one I picked years ago....the 1884 star in shield variety. If you look at the reverse shield upper left cornor what looks to be a cut star in the shield. Many series have been noted to have anomalies on them that are questionable as to how they got there. The 1884 reverse ☆ upper left shield. http://www.indiancentvarieties.com/1884_variety001.html
This 1880 Snow 8 is another example of ODD on a coin. http://www.indiancentvarieties.com/1880_variety008.html
I don't normally click on links, but I did for you. In my opinion, the anomaly on the example you are showing, is due to the lamination problem, not a star at all. But, that being said, yours does seem to match that photo. I don't work with IHC but you might want to submit it for authentication to confirm indianacentvarieties entry.
Yeah I understand totally about links..but the star is a listed variety for the date ,one of those things that happened at the mint.
I have something odd. It looks like additional fabric on Jeffersons knot between the ponytail and the collar. I have been told it's a common die clash.
The 1943 nickel is most probably the specimen with the most varieties. 78 some rpm , DDO's ,DDR's over date, etc... etc... not knocking your find have heard of this before myself. The old joke is" show me a 43 that isn't a variety " another favorite is "show me a 64 with a step" 64 nickels most minted ever FS nickel are near impossible to find.
I have more than a few of those other varieties. This one I have never seen listed before and now I have 4 of them.
I have a ty 2 proof silver 1942 struck with the proof die of a 42. As the obv. Die marker is found on the silver proof.
