What is this called?

Post by Eschaton » Fri Sep 01, 2023 9:39 pm

My brain wants to call the tapered planchet, but it's confusing since it's on the left AND right side of the reverse. Obviously, the right side is more prominent. Obverse looks totally fine. Any idea for what the technical name for this is called? Thanks

Looks like a misaligned die.

I was not paying attention to the actual strike, even though it's obvious, I was just looking at the rim. Can you give us some shots of the edge of the coin, (the reeded area), in a few spots?

Reeding is normal. Strike appears normal. Looks like a tapered planchet, except on all the tapered planchets I've seen it's been on both obverse and reverse of the coin and in one area, this is on only the reverse and in TWO areas.

Would love to hear the consensus from @messydesk, @vampicker, @RogerB, and the other guys who are into these kinds of things.

I don't think it's die or strike related.

I think it's a "tapered" planchet. (or whatever the technical term is for that)

Hard to tell in a slab, but if it is a tapered planchet, it would be a little light, Weigh it compared to a normal coin in the same slab

Not sure how a tapered planchet would give a strong strike on one side and a weak strike on the other. I also haven't seen a coin struck through schmutz that looks like this. Does AMER in AMERICA have any of that grease-filled look to it? Agree that the weight would be good to know.

If it's a defective planchet (too thin or irregular) the weight might reveal that by being too low. (Dollar blanks were sorted by machine.)
If weight is normal, then other options could include slight tilt to the bottom (reverse) die; uneven planchet hardness; other mechanical problem with press such as center stake wear, excessive die chuck play; incorrect pressure wedge adjustment.
(The reverse photo does not seem to be consistent with die filling. Photo shows symmetrical rim and peripheral letter weakness - nearly impossible to create with filling.)

Please post obverse photo.

23-P v11B.

Took the photo in such a way as to show the unremarkable appearance of obverse rim.

OK, in an extremely odd twist of fate, just came across this: same exact VAM but zero signs of the phenomenon.

John R, out of town at the moment, so don't have any other comparable coins to weigh on hand, or an accurate scale.

The obverse rims look pretty fat and the letters LI and Y look weakly struck. It also looks like you're missing flow lines on the left obverse just inside the rim. There's no real reason a tapered planchet has to be evenly tapered on both sides. The obverse side could have been nice and flat, while the reverse had some minor voids in it. Since you have another specimen of the same die pair in what seems to be the same holder, I guess weighing them when you have the opportunity is the way to go.

Sorry, I wasn't clear, that's just a photo I found, I don't have another comparable coin to weigh at the moment. Thank you all for your input 👍

The rim appears to be fairly well struck up, so I would lean toward a grease strike through.

Since the image is all the way at the top and there's a bunch of other images now, I figured I'd re-post it so everyone knows the image were talking about.
