    Look at the edge of the coin from his previous pic -

    [​IMG]


    High rims on each side, obv and rev, with a recessed (lower) space in the middle. That's not finning, that's a type of railroad rim due to a collar error.

    Now this picture does show some finning is present when the coin is viewed from the face side of the coin -

    - and finning is caused by excessive pressure. That's why it says what it does on the slab.

    But there's a whole lot more going on with that coin than just finning. Finning is pretty common, railroad rims are not. And I've never, ever, seen one where both are present on the same coin like it is with this coin.

    Doesn't mean there aren't some out there, just that I've never seen one before.

    I'm not sure if you are looking at that picture correctly. I'm not seeing a railroad issue there.
    But I will look more into it.

    Unless my eyes are seeing something that is not there the rim seem to be showing a martial UNUM.
    This definitely looks like a collar issue.

    Me I had a 1957 Ford Fairlane 500 convertible 312 Thunderbird engine, 3 on the tree ...now that's a car I'd love to have back.
    The guy I sold it to ran into the back of a #23 trolly at Erie & Germantown Ave in Philadelphia, Pa.
    Here's what they look like (I don't have a image of mine0 1957 Ford Fairlane 500.jpg

    Here is the biggest "finned" piece in my collection. This ian 1864 Lincoln campaign piece that subsequently made it into the Patriotic Civil War token listings.

    This one was probably struck after the election for 19th century collectors. It is made of gold filled copper, and yea, it's a rare one.

    And since others have posted cars with fins, it's hard to beat the 1959 Cadillac. No, it's not mine.

    Now please explain, and or confirm, to the folks that don't know that that fin is almost paper thin and that it stands virtually straight up from the rim. And if you were touch it or push on it, it would fold over like a piece of tin foil.

    Can you please show us a picture if your coin once again. Showing the entire front of the slab showing the raised metal.
    Thanks

    For coins and tokens that are struck with a closed collar, there three sides, the obverse and reverse dies and the collar that goes around the rim. If there is a narrow space between a die and rim, metal can flow into that space and be formed into a thin piece of metal called a fin or wire rim. This is really the result of a defect in the minting process. There should be no space between the edge of the die and the collar.

    The most famous fin or wire rim is the 1907 High Relief $20 gold with that feature.

    I have another one slabbed by PCGS, labeled "high finned rim" error.
    This one shows the fin better IMO.

    @GDJMSP
    Please look at the nickel again from a side view.
    See how the raised metal looks now?

    Agreed paddy, the other pic was deceptive, (not intentionally mind you), this one is not.
