    Unanswered: Are Lincoln's struck in a collar?

    I've been trying to learn the different parts of a coin. Like rim vs. edge, etc., and in doing so, I am wondering if I've got this right?

    First I had to look up coins with reeded edges and I found that they are struck in a collar that produces the reeded edge, then that collar separates into three pieces to allow the coin to come out.

    Since Lincoln blanks are sent through the upsetting mill, which creates the rim and edge of the coin... are they also struck in a collar that separates?

    I've never paid much attention to the rim and edges of Lincoln's, but recently I have been and I realize there's so much I don't know!

    They are struck in a collar. If they aren't they're broadstruck and grow bigger.

    Thank you Ed! So the collar is similar to that used on nickels, dimes and quarters... and it separates to let the coin fall through after being struck?

    I think the obverse die is the anvil die and the collar surrounds the anvil die, I'm not sure if it separates or not.

    I think they call it a "stiff" collar, maybe that means it does not move like part of the anvil???

    See if someone can explain it

    I found this on error-ref.com regarding stiff collar strike, but I have a hard time comprehending this.

    The information in the Error-Ref.com link makes it sounds like the collar actually rises and descends (probably to allow the coin to be ejected).

    "The hammer die can drive a coin completely into a fully deployed collar. Sometimes the collar is partly deployed. Sometimes the collar is partly depressed but then freezes in a partly deployed position."

    And as I remember most collars do NOT separate, but the Lincoln series collar does.
    Edit: Lincoln collar Does NOT separate. (Sheeesh)

    Thank you Cliff and Ed! This is great information to know, and part of the minting process that I have never studied. In error-ref.com's information, I see several times where the hammer die is typically the obverse die. But then that would change with the Schuler presses since they are inverted, which I think means horizontal.

    If I remember correctly - These days the hammer die is the obv and the anvil is the rev die... Since the coin edge is smooth the collar should be a single piece??? I believe Bob would know better than me!!!

    Thank you Jim! Maybe I'm being too techie, but I have a reason for asking about this. I have a 2018 with a rim situation that has made me think about how this could have happened. I will pic and post it by the next day or so, so we can have a look. It would be great for Bob to shine some light on this for us!
