"How much is this error coin worth?"

[Nevol]

Wow! So if one in really good condition turned up it'd probably go for quite a bit more. Sorry I was so stingy with my estimate. :angel:

Nice pick-up anyway. :yahoo::wavemulticolor:

Likewise Nevol, I obviously haven't been paying attention to them, I was miles off.

Maybe I overpaid There were 4 active bidders and two of them were quite upset (haha see what I did there) when they didn't win.  My first experience of a Facebook auction was not a particularly good one.

[Robster]

Cool error regardless.! :ok:

Facebook auction? Not whatsername's group, I hope?

I assume my planchet fault here in a 1971 50c is not all that amazing, but if any of you error-seekers want it its a give-away :-)



Cheers, the axeman!

TBH, it looks like PMD, judging from the blurry pic. If that's the case, not worth spending $1 to mail it anywhere.

And chance of better piccies?

What is PMD? Once I know what PMD is I will check and if its not, I will try for a better photo. Otherwise sounds like not worth the effort hey :-) Cheers.

"Post Mint Damage". THat is the coin has suffered some accident in circulation.

"Post Mint Damage". THat is the coin has suffered some accident in circulation.

Yeah, what he said. Sorry, I assumed everyone knew. My Bad.

To elaborate...

It looks like there's a cut in the coin. That, absent better imagery, suggests damage rather than a flaw, because...

Planchets are cut from a roll of metal. If that metal sheet has a flaw in it, generally being known as a cold shut, that flaw will take one of two forms.

It can be like a 'splice' where two pieces are rolled together and fail to properly bond into a single piece. or it can be like a chunk of metal pressed into the sheet, also not fusing into one intact whole. Think about how loaves of bread turn out depending on how the dough is handled.

Now, when you cut a row of planchets out of it, you'll get either a 'tear' across the row of planchets, which will typically show as a line that flakes away, or perhaps as an internal fault that eventually splits the coin in two, depending on the size and alignment of the join.

If its an inclusion, you will see the piece eventually fall out, leaving a crater where it used to be.

But what we see here appears to be neither of those. What it does look like is as if someone took a pair of sidecutters to the coin, after it was minted. If you look through the forum, you will find pictures of coins which were argued over for some time, eventually reaching a consensus that they were in fact caught up in some mechanism, perhaps in a counting or vending machine. There was no other rational explanation for what we saw, on many different coins yet with no consistency.

Now, in the event that this IS actually a flaw, here's what to look out for. Again, there's at least one example here someplace that shows it nicely if you can find it.

The inside of the gap will tell the story. If it has a rough look to it, like you would get if you split a piece of granite or concrete say, then it may be a flaw that opened up under pressure, or an inclusion that fell out. If it has a smooth look, like a saw cut, and especially if its shiny, then it pretty much can't be a planchet flaw.

Have a good, hard look at it. Get some decent pics, or if you can't, and you think its real, send it to a member with a USB scope to image (or buy one, they're not that dear, and a pretty handy tool to have).

Does all that make sense?

Good summary.! Is a valley or depression in a coin considered as a cold shut or a planchet flaw. (mainly in pre decimal copper).

Good summary.! Is a valley or depression in a coin considered as a cold shut or a planchet flaw. (mainly in pre decimal copper).

It could be a cold shut, or it could be a strikethrough.

The way to tell is the edges.

Think of the difference between a cliff and a rolling hill. The cliff has a sharp edge and a relatively steep drop-off. The hill is more eroded, and curved.

Well, the cold shut leaves a cliff-like edge, because the pieces were literally one when struck, and when it falls out it leaves that sharp delineation. The strikethrough is more gentle, as the oil or whatever contaminant was on the coin spreads out and absorbs the energy.

Also, the bottom of the crater is a good indicator too. Again, the strikethrough is smoother. And generally shallower overall. Cold shuts tend to be relatively large, and extend deeper into the coin, though not always, whereas fluids on the surface have nothing to stop them spreading out, so they can be quite thin.

Oh, and both are flaws. Anything that isn't a variety or die damage error is a flaw.

Well we have heard how much Mark's 2001 20¢ upset is worth. Anyone want to hazard a guess on the value of mine.
I went to my upsets tray today to check that toe 2010 50¢ I am about to list is not better than any i have kept and found this one I noodled some time back. I had completely forgotten about it (old age strikes again)!

[Unicorn]

Very very nice Jeff!
It looks is great condition.
