Well, it's always worth a hundreth of a dollar............. Smile

Maybe a trial strike. The experts on this forum might be able to tell you with a MUCH better picture.

more than likely a trail strike or it might have been a strike from the end of the day as the machine was slowing down it stamped the coins each time with less pressure causing the details to slow spread out and fade more and more on each stamp.
but that's just my personal opinion

Can you get a better pic of both sides?

Is that a second LIBERTY at an angle above the other?

Is this coin under weight? A better image would help to see what it is. Its not a trial strike as the rim where the die meets the edge is fully set up. I need more images to see what were are looking at.

As you surmised, it was struck through a late-stage die cap.

Mr Diamond, please explain your terminology "struck through a late-stage die cap" , for us mere mortals. As always, I am just trying to learn !!

Thanks

A die cap forms when a newly-struck coin sticks to a die and proceeds to strike a succession of planchets. In this case the die involved was the obverse (hammer) die. As it strikes one coin after another, the floor of the cap gets thinner and thinner, allowing more and more of the design to bleed through. When a lot of the design bleeds through, as in this specimen, we conclude that it was struck through a late-stage die cap.

Mike, thank you for an excellent explanation of what happens in the "die-cap scenario. Is there any particular reason for the coin sticking to the die? I suspect there might be grease, or similar, but if not, they why? Could it also be in the early die state, where the "sharp", (non-worn state), features of the "new" die would casue sticking? I think you know what I'm trying to ask, but not being very clear. Thanks,
Dick

Nobody really knows why some coins stick to the die.

CoinboyJay · Member

I get it...... Very Happy

Thanks Mike.

The ones I would like to find are the ones that caused the die cap coins.

Those are the real keepers. How they got out of the mint is a mystery to me. Maybe the mint worker got mad and tossed them into the coin bin in a rage of anger, or maybe they become dislodged and ended up there.

One thing you need to keep in mind that a lot of the coins the grading service call "die caps" are one-strike wonders. This applies to many so-called caps with a crisp brockage of the obverse design on the reverse face. These are created in a single strike when a planchet is fed in on top of an already-struck coin and both are struck out-of-collar. The top coin curls up toward the hammer die to form a thimble shape. The companion of such a coin is a double-struck reverse die cap. Quite a few uniface die caps are also 1-strike wonders.

Nice update on information Mike. But the capped dies/bottle cap ones are still worth more than the capped die strikes. The thought of a one strike wonder had never came to mind.
