Offcenter nickel with "reeded" edge. Thoughts?

scubafuel

Here's an offcenter nickel I've owned for a while, because I was never quite able to explain it.

No-Date, D mint. But given the other errors I received with this one, probably a 1999 or 2000.
70% offcenter, with a "reeded" edge in 3 areas: The edge of the offcenter strike is reeded (see pics), and 2 areas of the blank edge are as well.
The reeding is not vertical, but slightly diagonal, as if it was applied when the coin was tilted at an angle.

So, given that there are reeds at the edge of the offcenter strike, it's almost certain this happened after the strike. But I believe it happened while still in the mint. (these errors I bought came from mint bags at the time) Any guesses as to what machinery could have caused this?

See this all the time - it's damage from a
counting or rolling machine.

the off center strike shape gets caught in the
machine, and that 'reeded' edge you see is
the damage from the coin getting jammed.

....and it's usually, but not always,
opposite the O/C strike, which is
why the coin gets jammed in the
first place, sometimes.

Got it, thanks Fred. I'm surprised I haven't come across something like this more often.

Thanks! What part of the rolling machine does this?

There is a counting wheel within the automatic counter that causes that damage, I’ve seen it on cents before.

And to think I thought the US Mint weighed their coins, not count every one. I mean, I've searched $200 bag nickels but never bothered counting to see if there were exactly 4000 nickels.

Can @fredweinberg or someone else post another example of this pseudo reeding effect? I’m having trouble finding another online.

I don't have any right now - they come in
with mostly larger groups of errors that I
buy.

They've been listed on Ebay before with
that description, but I don't think there
are any up there right now.

I think the Mint does go by weight. The coin processors (Brinks, Loomis, NF String, etc.) do the rolling.

This has some marks. Similar?
