I had some experts who specialize in errors look at this coin. I was actually told a lot of prooflike errors come out of Bulgaria.

Also, I was told most in collar double strikes don't rotate while it's in the die, they actually get ejected into the tote bin and then go back into the press later on. As a result, you will see lines or marks on the edge of the coin that were caused when the coin re-enters the chamber.

This coin shows scuff marks around the edge which indicates it was ejected and then later re-entered the collar for the second strike. Because of this, the experts believe this coin is an authentic error.

Are US proof coins really ejected into tote bins?

Whether it gets ejected into a tote bin or something else isn't the point. A "tote bin" may be incorrect. The point is the coin gets ejected from the collar and then re-enters later on for the second strike and the edge of the coin gets scuffed up re-entering the chamber.

This is not the first double struck proof cent. They are all double struck. But I found an image years ago of one double struck one time not in the collar.

This is the only Two Cents I seen through the years in images.

Apologies for the question, I'm just trying to understand how this might have happened.

I'm no expert, but thought proofs were struck two or more times as needed back to back. They can move in process. To eject it after each strike and reenter and then align them one by one seems a tad bit labor and time consuming. Thanks, Doug.

Adding: A mint assisted error is done by ejecting and reinserting manually.

The coin is held in place in the collar for however many times it is struck by the die (this is being called the 'first strike' even though it may technically be 2 or 3 strikes in a row). It is then ejected from the collar. Later on, it somehow re-enters the chamber in a different position and is held in place by the collar while it gets struck however many more times (this is being called the "second strike").

How it re-entered the chamber after it was fully struck the first time is anyone's guess, but it is likely an error from a mint employee, whether it was intentional or not. I can imagine a coin unintentionally being transferred from the ejected "bin" back to the hopper of blank planchets to go through the die striking process all over again, this time at a different position.

EDIT: Or the "experts" were wrong, and it actually did get struck once, rotated in the collar, and then struck a second time. I could see how the coin rotating in the collar would scuff up the edges more so then getting ejected and reentering the chamber. EDIT 2: But there was only about 15 degrees of rotation between the strikes, but there is more like 90 degrees of scuffing on the edge. Now I'm not sure what to think

It couldn't have stayed in the collar between the first strike and then the rotated second strike. If it had then the anvil side would have remained "locked" into the die. Since both sides are rotated it must have left the collar between the strikings.

Possibility: It was struck, the anvil die rose up pushing it out of the collar but the feed fingers failed to function. The anvil die retracted leaving the coin suspended above the coining chamber (since the struck coin is exactly the same diameter as the hole in the collar it tends not to drop back in like a planchet would.) The hammer comes down forcing it back into the collar and in the process it rotates and the second strike is completed.

Mithril, that's awesome! Are you going to keep it or sell it? For me, I would keep it, but that's just my opinion.

I was planning on putting it up for auction, but I keep getting more and more attached to this coin so now I am not sure what I will do. I think the high grade, DCAM, and significant enough rotation to see two full "LIBERTY" and "1998" combine to give this coin exceptional eye appeal.

By comparison, all of the other double struck in collar proof coins I have seen have either had very slight rotation and/or only obverse rotation. This coin has by far better eye appeal then all of those other examples I have seen.

Definitely a nice find with exceptional eye appeal.

I feel for you with the "Save or Sell" quandary. But if you sell, that gives you more $ammo to find other varieties or errors.

Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.
